When is cellular respiration performed?
Cellular respiration occurs in all living cells, at all times, to generate energy in the form of ATP. The process involves breaking down glucose molecules in the presence of oxygen to produce ATP, carbon dioxide, and water.
Explain why at certain times of a day there is no movement of oxygen or carbon dioxide through stomata even though they are open.?
It might be that at certain times there is a balance between the amount of photosynthesis and the amount of cellular respiration going on. Photosynthesis produces the oxygen that respiration needs. Respiration produces the carbon dioxide that photosynthesis needs.
What is the cell organelle that is the site of cellular respiration which produces ATP?
The cell organelle responsible for cellular respiration and ATP production is the mitochondrion. Mitochondria are known as the powerhouse of the cell because they generate energy through processes like the citric acid cycle and oxidative phosphorylation.
How are photosynthesis and cellular respiration different?
Photosynthesis:occurs in plants and some bacteria.only occurs in the presence of sunlight/UV lightoccurs within the chloroplasts.requires chlorophylluses water, light energy and carbon dioxideproduces oxygen and glucose (which are the reactants of cellular respiration)captures light energy to store as chemical energybuilds up the plant's energy storeschemical formula is 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2is an anabolic reaction, i.e. simple molecules are built up into complex onesoccurs in two phases: the light and dark reactionsuses NADP to carry hydrogen ionsis an endothermic processresults in the production of carbohydratescaptures light energy and converts it to chemical energyenergy is solar energy converted to chemical energyCellular Respirationoccurs in plants and animals.occurs at all times in all living organismsoccurs within the cytoplasm and mitochondria.does not require chlorophylluses oxygen and glucoseproduces energy (in the form of ATP), carbon dioxide, and water (which are the reactants of photosynthesis)chemical formula is C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy (ATP)is a catabolic reaction, i.e. complex molecules are broken down to simpler onesoccurs in three phases: glycolysis, Krebs and the ETSuses NAD+ to carry hydrogen ionsIs an exothermic process.Involves the use/consumption of carbohydratestakes the chemical energy resulting from photosynthesis and breaks it down, releasing energyenergy is the stored chemical energy that originated from photosynthesis; this chemical energy is converted to other kinds of energy like heat and motion (energy required for cellular processes to occur.)
Do cells go through cellular respiration?
cells in mammals respire all the time to keep them warm blooded and keep breathing etc, all animals respire all the time, but some cells are unable to respire due to the fact they lack mitochondria plant cells do respire, but they do not need to at all times, because they do not need energy to move or stay warm.
Which organisms undergo both photosynthesis and cellular respiration?
Plants, algae, and cyanobacteria are examples of organisms that can undergo both photosynthesis and cellular respiration. During the day, they perform photosynthesis to produce energy from sunlight, and at night or during times of low light, they switch to cellular respiration to generate energy from stored carbohydrates.
What does cellular respiration occurs in the presence of?
Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.
Does cellular respiration occur at night?
in happens day and night. but it depends on the type of plant...........
When is cellular respiration performed?
Cellular respiration occurs in all living cells, at all times, to generate energy in the form of ATP. The process involves breaking down glucose molecules in the presence of oxygen to produce ATP, carbon dioxide, and water.
Why do we do cellular respiration?
Cellular respiration is the process by which cells produce ATP for energy. Also, cellular respiration is much more efficient than fermentation, the process by which single celled organisms. (Cellular respiration produces 18 times more ATP than fermentation) Essentially, without cellular respiration is what keeps the cells in your body functioning.

What are the starting materials and products of photosynthesis and cellular respiration?
Photosynthesis consumes carbon dioxide and water to create oxygen and organic molecules. Tt is endergonic, H2O is oxidized and the CO2 is reduced, ETC is in the thylakoid membrane in the chloroplast, protons move from thylakoid space into stroma, and ATP is synthesized into glucose.Cellular respiration consumes oxygen and organic molecules to create carbon dioxide and water. It is exergonic, glucose is oxidized and O2 is reduced, ETC is in the cristae (inner membrane) in mitochondria, protons move from the inner membrane space into the matrix, and glucose if catabolized to synthesize ATP.
How often does respiration occur in plants?
Respiration in plants occurs continuously, day and night, as they convert glucose and oxygen into energy, carbon dioxide, and water. While photosynthesis primarily takes place during daylight when light is available, respiration does not depend on light and is essential for plant growth and metabolism at all times. This process allows plants to utilize the energy stored in sugars produced during photosynthesis.
Which generates more energy from the sugar molecule aerobic or anaerobic cellular respiration?
Aerobic cellular respiration produces a net gain of 36 ATP per glucose molecule. Anaerobic respiration produces a net gain of 2 ATP per glucose molecules.Aerobic cellular respiration produces 15 times more energy from sugar than anaerobic cellular respiration. :-)
Does a plant use carbon dioxide in reactions during environmental light?
Yes; at the most basic cellular level, the reactions photosynthesis and cellular respiration both occur during times of light; the former utilizing the sun's energy and the latter as part of the metabolic process of organisms that convert nutrients to ATP.
Does respiration occur at night?
Yes, of course =D. Cellular respiration must take place at all times in order to maintain functionality within a cell.
What is the cell organelle that is the site of cellular respiration which produces ATP?
The cell organelle responsible for cellular respiration and ATP production is the mitochondrion. Mitochondria are known as the powerhouse of the cell because they generate energy through processes like the citric acid cycle and oxidative phosphorylation.
