Answer:

please select me as brain list

Explanation:

Solution:

The primary acceptor of CO2, is a 3 carbon compound phosphoenol pyruvic acid. Addition of CO2, to any compound is called carboxylation. In C4 cycle, CO2, combines with phosphoenol pyruvic acid to form oxaloacetic acid. The enzyme is phosphoenol pyruvate carboxylase (PEPCo). The oxaloacetic acid breaks up into pyruvic acid and CO2, which combines with RUDP to form PGA as in Calvin cycle.
