Question

What is the role of the PEP carboxylase enzyme during both CAM and C4 photosynthesis? to capture CO2 in the form of 3-carbon organic acids to create ATP to capture CO2 in the form of HCO3 to capture CO2 in the form of 4-carbon organic acids

Answer 1

To capture CO2 in the form of 3 carbon organic acid

Step-by-step explanation:

carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.
