Question:
The first acceptor of $CO_{2}$ in $ C_{4}$ plant is:
The first acceptor of $CO_{2}$ in $ C_{4}$ plant is:
Updated On: Aug 15, 2022
- pyruvic acid
- phosphoenol pyruvic acid
- acetic acid
- oxaloacetic acid
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$C _{4}$ plants show $CO _{2}$ acceptors at two levels but the first acceptor of $CO _{2}$ is a 3C -compound which after acceptance of $CO _{2}$ converts into a $C _{4}$ plants is given to them. The first $CO _{2}$ acceptor is a 3C-compound.

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)
