Question

What does ATP add to the Calvin-Benson cycle?

A) Carbon atoms

B) Hydrogen atoms

C) chemical energy

D) electrons

Answer 1

ATP adds C) chemical energy to the Calvin benson cycle

Answer 2

The correct answer is option C) chemical energy.

Explanation:

In the Calvin cycle or Calvin-Benson cycle ATP adds chemical energy to convert three molecules of CO₂ to one molecule of the 3- carbon sugar. Later in the regeneration stage ATP is again required. In the Calvin-Benson cycle, nine ATPs are converted into nine ADPs, out of which six ATPs are used during the fixation stage and rest three in the regeneration stage.
