Which of the following does not occur during the Calvin cycle?

Carbon fixation

Release of oxygen

Oxidation of NADPH

Regeneration of the CO2 acceptor

Consumption of ATP

Release of oxygen

Explanation:

Calvin cycle or the C3 cycle is the sequence of reactions taking place in the sequential and cyclic manner.

The Calvin cycle takes place in the stroma of the chloroplast and is associated with the production of glucose during photosynthesis.

1. Carbon fixation is the first step of the cycle which fixes the atmospheric carbon into the intermediate compounds.

2. Release of oxygen- the oxygen is not released during the cycle but is released in the light-dependent phase of photosynthesis.

3. The NAPPH is fixed in the Calvin cycle.

4. The carbon dioxide molecule acceptor molecule called RuBP is regenerated in the Calvin cycle.

5. The ATP is consumed in the Calvin cycle during reactions.

Since oxygen is not released during the cycle, therefore, is the correct answer.

it is either c or d and i know for sure it is not a or b
