Respiration is a crucial process in plants that produces energy and plays a significant role in plant health and growth. Environmental factors such as age, temperature, sunlight, water availability, oxygen availability, and physical damage can affect respiration rates. Plants use solar energy conserved during photosynthesis to produce energy through respiration, which can be either beneficial or detrimental depending on the specific tissues and environmental conditions.
Rising atmospheric carbon dioxide concentration significantly influences plant growth, development, and biomass. Increased photosynthesis rate and lower stomatal conductance have positive effects on plant growth. The ratio of respiration to photosynthesis also influences relative growth rates, with some crops and wild plant species experiencing a decrease in respiration rates with increasing growth rates. Photorespiration is one of the largest metabolic fluxes in plants, with rates as high as 25% of photosynthetic rates in C3 leaves at 25°C.
In agriculture, waterlogging and soil oxygen availability can affect root respiration, which can affect plant growth. The process of respiration involves using sugars produced during photosynthesis plus oxygen to produce energy for plant growth. The utilization of energy produced by respiration is important for crop growth and development under high temperatures, but it has limitations.
Plant growth is closely related to both photosynthesis and respiration, as there is no growth without photosynthesis and respiration. Therefore, plant growth is largely a function of the gain of sugars from photosynthesis and the use of those sugars by respiration. A thermodynamic model describing the relation between plant growth and respiration rates is derived from mass-and enthalpy-balance equations.
📹 Cellular Respiration: How Do Cells Get Energy?
Cellular respiration is the process through which the cell generates energy, in the form of ATP, using food and oxygen. The is a …
What are the benefits of cellular respiration in plants?
Cellular respiration is the process by which plants and animals convert sugar into energy, which is then utilized for cellular function. This process is of great importance to the overall health and productivity of the cells.
What happens to a plant cell during cellular respiration?
Cellular respiration is a metabolic process whereby cells convert glucose into energy through a chemical reaction involving the oxidation of glucose and oxygen. The net result of this process is the production of carbon dioxide, water, and adenosine triphosphate (ATP) as by-products.
What is the role of respiration in the growth and development of plants?
Photosynthesis generates glucose, which provides energy to plants. Respiration, a process where plants release oxygen and carbon dioxide, uses glucose and oxygen as substrates for cellular respiration. This process produces adenosine triphosphate, the energy currency of plant cells. This energy is used to produce phytohormones, such as auxins, gibberellins, and cytokinins, which promote plant growth and development. Both photosynthesis and respiration are crucial processes for plants, as they are interrelated and essential for their overall growth and development.
Why do plants need cellular respiration too?
Plants require cellular respiration to facilitate the release of glucose-bound chemical energy and the subsequent production of ATP, which is essential for the sustenance of cell metabolic activities. This process necessitates the presence of carbohydrates and oxygen, thereby requiring that plants possess the capacity to locate these resources.
Why is respiration needed for growth?
Respiration is the process by which cells convert glucose, a sugar obtained from food, into oxygen, which is used for growth, repair, and movement. The process produces water and carbon dioxide, which are then excreted. People often confuse respiration with breathing, as respiration requires oxygen, which animals obtain through breathing. Understanding respiration requires understanding cell structures and the major organelles responsible for it.
What is cellular respiration in plants?
Cellular respiration is a metabolic process whereby plants transform oxygen and glucose into adenosine triphosphate (ATP), a vital source of cellular energy, and carbon dioxide.
What is an advantage of cellular respiration?
Cellular respiration is a vital process that generates usable ATP energy to support various body reactions, especially those that require energy input. It involves three main steps: glycolysis, the citric acid (TCA) or Krebs cycle, and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
Glycolysis breaks down glucose into pyruvate, a three-carbon structure, in the cytoplasm. This is then converted into acetyl-CoA in the mitochondrial matrix, which is then combined with oxaloacetate to form citrate. The Krebs cycle takes two turns to break down the original glucose, as each molecule produces two pyruvate molecules.
Why is respiration good for plants?
Plants need to breathe to function and absorb gases from the atmosphere. They use oxygen for aerobic respiration and carbon dioxide for photosynthesis. Plants don’t have lungs to inhale and exhale the air, but they ‘breathe’ in and out oxygen and carbon dioxide. Oxygen is used in aerobic respiration, where food molecules are broken down to release energy for growth. Plants absorb these gases through tiny breathing pores in their leaves, moving through diffusion from high concentration to low concentration. Roots also need oxygen, which they absorb from air spaces in the soil, making well-aerated soil essential for good growth.
How does cellular respiration affect plant growth?
Plant respiration is a process where plants use the sugars produced during photosynthesis and oxygen to produce energy for growth. It is the opposite of photosynthesis, where plants produce their own food to survive. In natural environments, plants use carbon dioxide to produce sugars and oxygen, which are then used as energy. Respiration occurs in the leaves, stems, and roots of the plant, while photosynthesis occurs in the leaves and stems.
What is the result of cellular respiration in plants?
Cellular respiration is a metabolic process whereby plants transform oxygen and glucose into adenosine triphosphate (ATP), a vital source of cellular energy, and carbon dioxide.
What happens to plants during respiration?
Plants require gases to function, like humans, to breathe. They require two key gases: aerobic respiration, where food molecules are broken down to release energy, and photosynthesis, where the sun’s energy is harnessed to produce food. Carbon dioxide is released as a waste product, while oxygen is used in photosynthesis. Plants’ internal structure allows for easy gas exchange and movement, similar to how oxygen diffuses in for respiration and waste gases diffuse out.

We like to pin comments for clarifications, updates, or corrections – while we recognize it’s very common to hear that “glycolysis happens in the cytoplasm” and it’s what we label- it would be far more specific (and better!) to have specified “the cytosol of the cytoplasm.” Why? We made a Short to explain: youtu.be/qZa8Rtsyt2g and at 0:36, we made a correction card to specify ATP as a “type of nucleotide” instead of “nucleic acid.” While nucleotides are monomers for nucleic acids, ATP doesn’t form the chains you see in nucleic acids like DNA and RNA (and its function differs as article shows). Our ATP article specifies it as a nucleotide derivative.
I study from my textbook and classes, then I watch your articles to get a general idea of all the things I learned and kind of recap; the best part is when I finally realize something in your article that explains something I couldn’t catch in class and then just say “OHHHHHHH, that’s why”, this really helps me learn so much, thanks for all your hard work!

Your articles have been posted they make people learn things and not just study a kind of knowledge, I mean bro you really make me learn biology “which I love ” in a fun way! and not in the classic and boring way of school study! which is just about exams, tests, homework etc…..thank you so much I really appreciate your presence in life:face-red-heart-shape:
If you are wondering how electrons allow proteins to pump protons, here’s how. The NADH donates 2 high energy electrons. The electrons are transported through redox center, however, the redox centers have a different electron affinity, which creates a small amount of energy. The energy is stored and used to pump protons.
As usual great. This is the way my mind wanders: I took a class in how to make sauerkraut, and I wondered about the biochemistry of fermentation, then I got back into the whole Krebs cycle thing again. ATP synthase is enormously fascinating. I’m just some guy interested in this stuff and these articles are always great.
you should do a youtube website were you talk about all lifesiences not only cells.when you guys explain things you make it fun and it helps undertsand,it helps me like and enjoy sciences.so please take my suggestion so that you dont only help me but the other people that love your your website .im currently in 10th grade doing lifesciences and i enjoy your explanations better than my teacher .Thanks for being Awsome.
Does the article talk about how glucose binds to glycolytic enzymes to create pyruvate, or did I just miss that? It was hard for me to move on without first knowing how the glucose made the Pyruvate. I knew it was an byproduct of glycolic but couldn’t connect the dots until I did a little more research. Over all it’s still a really good article and helped me a lot when studying for my micro exam.
So I know this is a slightly older article, but your clip about cyanide (CN-)affecting ATP synthesis got me thinking to something: Pyrazole (I think 2-Pyrazoline) is C3H4O2 when occurring naturally (there are very few sources of this). The synthetic stuff manufactured for pharmaceutical and agricultural use as an active reagent is (if I remember reading this correctly) lacking a couple Hydrogen from the molecule. Now to the question: Is there a process like digestion that could convert the potentially less stable compound into cyanide and a secondary product?

This is such a complicated process that I really think you shouldn’t have tried to explain it all at once, but rather in stages, explaining the whole process first in very basic detail that is easy to understand, before building on it and adding detail. Like for example, you could sum up the entire first step, Glycolysis, as just “Glucose is converted into pyruvate”. Or you could sum up the entire second step, the Krebs Cycle, as “Pyruvate is converted to Acetyl CoA, which is then further acted upon to produce Carbon Dioxide, NADH and FADH2”. There’s no need to know the details like the exact number of different molecules that are produced, or the exact details of how everything is performed, not until your viewers understand the basics at least.
