Question 1 of 120 answered
Which enzyme is the primary carboxylase in the C3 photosynthetic pathway?
Incorrect
Correct answer: Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase)
C3 plants fix CO2 directly via Rubisco, producing $3$-phosphoglycerate ($3$-PGA). PEP carboxylase is the initial carboxylase in C4 and CAM pathways.
