During the light-independent reaction, carbon dioxide is fixed by adding it to a
O A) 2-carbon compound
OB) 3-carbon compound
OC) 4-carbon compound
OD 5-carbon compound

D) 5-carbon compound

Explanation: During the light independent reactions, the first step in the cycle is carbon dioxide fixation in which three molecules of carbon dioxide is fixed into three molecules of a 5- carbon compound known as ribulose 1, 5- bisphosphate in a reaction catalyzed by ribulose 1, 5 -bisphosphate carboxylase (rubisco)
