PEP is primary `CO_(2)` acceptor in

A

`C_(4)` plants

B

`C_(3)` plant

C

`C_(2)` plants

D

both `C_(3)` and `C_(4)` plants

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `C_(4)` plants have evolved PEP as primary acceptor of `CO_(2)` to avoid the sensitivity of RuBP carboxylase-oxygenase to high concentration of oxygen, so that they can avoid photorespiratory loss of `CO_(2)` occuring in them.
Other option (b),(c) and (d) are incorrect. PEP is not primary acceptor in them.
