Question:
Step at which NADPH is required in Calvin cycle is
Step at which NADPH is required in Calvin cycle is
Updated On: Jun 21, 2022
- carboxylation
- regeneration
- reduction
- phosphorylation.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
During Calvin cycle, biphosphoglyceric acid is reduced by NADPH through the agencyofenzymeglyceradehyde3-phosphate dehydrogenase. It produces glyceraldehyde 3-phosphate or 3-phosphoglyceraldehyde.

Photosynthesis in Higher Plants
Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
