D) pyruvate carboxylase

Question

What is the name of the enzyme that catalyzes the reaction shown below? 
A) ribulose bisphosphate carboxylase 
B) acetyl-CoA carboxylase 
C) glyceraldehyde-3-phosphate dehydrogenase 
D) pyruvate carboxylase

Quizplus · Accepted Answer

The reaction shown in the image is the carbon fixation step of the Calvin cycle, which is catalyzed by the enzyme ribulose bisphosphate carboxylase (RuBisCO). B is incorrect because acetyl-CoA carboxylase is involved in fatty acid synthesis. C is incorrect because glyceraldehyde-3-phosphate dehydrogenase is involved in the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate in glycolysis. D is incorrect because pyruvate carboxylase is involved in gluconeogenesis.
