Question:
Fixation of one molecule of $ CO_{2} $ through Calvin cycle requires
Fixation of one molecule of $ CO_{2} $ through Calvin cycle requires
Updated On: Jul 27, 2022
- 3 ATP and 3 $ NADPH_2$ molecules
- 3 ATP and 2 $NADPH_2$ molecules
- 2 ATP and 1 $ NADPH_2$ molecule
- 1 ATP and 2 $NADPH_2 $ molecules
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$2$ ATP are required during conversion of PGA to $1,3$ diphosphoglyceric acid and $1$ ATP during conversion of glyceraldehyde phosphate to ribulose biphosphate. $2 NADH _{2}$ molecules are utilized for converting $1,3$ diphosphoglyceric acid to glyceraldehyde phosphate.

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)
