Question

Which of the following best describes the function of the Calvin Cycle?

A. mediating anaerobic respiration

B. Converting ADP to ATP

C. Producing carbohydrates from CO2

D. Deriving energy from glucose

I am split between C and D.

I know in the Calvin Cycle CO2 is converted into sugar. And in the bigger picture and its function during photosynthesis is that it allows the plant to store energy as glucose ( the carbohydrate of sugar)

Answer 1

Ans) Here, in this question they asked specifically about the functions of Calvin cycle or C-3 cycle. So the answer is OPTION C.

• Calvin cycle is a part of dark reaction which occurs in stroma or matrix.
• It helps to produce carbohydrate using the products of light reaction.
• Dark reaction include C3 and C4 pathways.

In Calvin cycle, it is completed through

1. Carboxylation
2. Reduction
3. Regeneration.

The NADPH and ATP produced in light reaction is used to reduce CO_{​​​​​2} to Carbohydrate.

In this cycle, 6 molecules of CO_{​​​​​2} is used to obtain 1molecule of glucose.
