Question

For the synthesis of one molecule of sucrose, how many ATP molecules are required in reduction step of the Calvin cycle?

• A. 24 ATP
• B. 18 ATP
• C. 2 ATP
• D. 12 ATP

Answer 1

The correct option is A 24 ATP

The ATP molecule required in reduction step of Calvin cycle is 24.

Correct option is 24.

Here, 6 ATP is required for 3 carbon sugar. In sucrose 12 carbon are present .

So, 6 x 4=24 ATP.

Hence, the correct answer is 24.
