D) phosphoglycolate
E) malate

Question

Quizplus · Accepted Answer

Rubisco, the enzyme responsible for carbon fixation in photosynthesis, can also act as an oxygenase, incorporating oxygen into RuBP (ribulose-1,5-bisphosphate). This reaction produces one molecule of 3-phosphoglycerate and one molecule of phosphoglycolate, the latter being the intermediate formed in the oxygenase reaction.
