Question

which compound is produced during carbon fixation?
pga
g3p
rubp
c₆h₁₂o₆

Explanation:

In the Calvin cycle (carbon fixation), RuBP (ribulose - 1,5 - bisphosphate) combines with \(CO_2\) to form an unstable intermediate which immediately splits into two molecules of 3 - phosphoglycerate (PGA). G3P (glyceraldehyde - 3 - phosphate) is produced later in the reduction phase, and \(C_6H_{12}O_6\) (glucose) is the end - product of multiple cycles. RuBP is the acceptor, not the product of carbon fixation. So the compound produced during carbon fixation is PGA.

Answer:

A. PGA
