Which of the following equations holds true for acidification reactions of CAM pathway?

Text Solution

Verified by Experts

The correct Answer is:
D
Crassulacean plants have developed a unique mechanism to perform photosynthesis without much loss of water. They perform acidification or dark fixation of `C_(2)` during night and deacidification during day. During night. When acid (PEP) to form oxaloacetic acid (O A A) in the presence of enzyme PEP carboxylase. OA A is subsequencly converted to malic acid in the presence of enzyme malic dehydrogenase. Malic acid produced in dark as a result of acidification is stored in the vacuoles. During day. When stomata are closed, the malic acid is decarboxylated to produce pyruvic acid and evolve `CO_(2)` (deacidification)
