Detailed explanation-1: -The carbon dioxide acceptor in CAM plants is Phosphoenol pyruvic acid (PEP) during the night and Ribulose bisphosphate is carbon dioxide acceptor during the daytime.

Detailed explanation-2: -Crassulacean Acid Metabolism (CAM) Photosynthesis In this pathway, stomata open at night, which allows CO2 to diffuse into the leaf to be combined with PEP and form malate. This acid is then stored in large central vacuoles until daytime. During the day, malate is released from the vacuoles and decarboxylated.

Detailed explanation-3: -In the CAM pathway, plants take CO2 during the night through the stomatal opening. It is converted to malic acid (4 carbon compound) and stored in vacuoles.

Detailed explanation-4: -CAM plants temporally separate carbon fixation and the Calvin cycle. Carbon dioxide diffuses into leaves during the night (when stomata are open) and is fixed into oxaloacetate by PEP carboxylase, which attaches the carbon dioxide to the three-carbon molecule PEP.

Detailed explanation-5: -In order to meet their needs to combine the Sun’s energy with CO2 from the air, CAM plants take in CO2 at night and store it in the form of a four-carbon acid called “malate.” Then the malate is released during the day, where it can be combined with the ATP and NADPH created by the Sun’s energy.
