Do cellular respiration and photosynthesis occur at the same time?

Answer 1

Cellular respiration is carried out by every cell in both plants and animals and is essential for daily living. It does not occur at any set time, and, at the same point in time, Neighboring cells may be involved in different stages of cellular respiration. Cellular respiration is an exergonic reaction, which means it produces energy. It is also a catabolic process - it breaks down polymers into smaller, more manageable pieces. The ultimate goal of cellular respiration is to take carbohydrates, disassemble them into glucose molecules, and then use this glucose to produce energy-rich ATP molecules. The general equation for cellular respiration is: one glucose molecule plus six oxygen molecules produces six carbon dioxide molecules, six water molecules, and approximately 36-38 molecules of ATP.

Localisation Of Cellular Respiration

a) Glycolysis occurs in the cytoplasm.

b) Kreb's cycle and oxidative phosphorylation in the mito chondrion and hyrolysis of ATP at the sites of the biological activity.

c) The reactions of hexose-mono phosphate pathway and activation of pyruvic acid to produce acetyl CoA.

Answer 2

Plants perform both cellular respiration and photosynthesis during the day, but only perform cellular respiration during the night because of the lack of light.

Answer 3

yes. because plant cells perform photosynthesis and cellular respiration. usually they perform photosynthesis and use some of the products of that to perform cellular respiration.

Answer 4

Photosynthesis and respiration are reverse processes of each other , but yes, they can happen at the same time.

Answer 5

Yes . These all occurs at same time . But in night photosynthesis does't occurs.

Answer 6

No, different directions.
