Question:

Which stage of the Calvin Cycle utilizes ATP?

Options:

1. Carboxylation
2. Reduction
3. Regeneration
4. Both 2 and 3

Solution:

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts during photosynthesis. It involves three stages: carboxylation, reduction, and regeneration. In the carboxylation stage, carbon dioxide is fixed into an organic molecule, which is then converted into glyceraldehyde 3-phosphate (G3P) in the reduction stage. Both these stages require energy in the form of ATP and NADPH, which are generated in the light-dependent reactions. In the regeneration stage, some of the G3P molecules are used to regenerate the original organic molecule, while others are used to synthesize glucose and other sugars. The regeneration stage also requires ATP. Therefore, both the reduction and regeneration stages of the Calvin Cycle utilize ATP.
