How Does Carbon Fixation Differ Between C₃ and C₄ Plants

question 36

Multiple Choice

How does carbon fixation differ between C₃ and C₄ plants?

• A)C₄ plants undergo carbon fixation by carboxylation of a four-carbon substrate (oxaloacetate),while in C₃ plants,a three-carbon compound (phosphoglycerate)is carboxylated.
• B)Both C₃ and C₄ plants involve carboxylation of ribulose-1,5-bisphosphate by rubisco;but in C₃,the first stable intermediate is 3-phosphoglycerate,and in C₄,it is oxaloacetate.
• C)C₃ plants don't undergo photorespiration,but C₄ plants do.
• D)Rubisco is the primary enzyme that catalyzes carbon fixation in C₃ plants,and phosphoenolpyruvate carboxylase can catalyze carbon fixation in C₄ plants.
