Much of the carbon dioxide that you expel in your breath comes from reactions catalyzed by which two enzymes of the citric acid cycle?
Succinyl CoA Synthetase and Aconitase
Malate Dehydrogenase and Succinyl CoA Synthetase
Fumarase and Succinate Dehydrogenase
Aconitase and Malate Dehydrogenase
Isocitrate Dehydrogenase and α-ketoglutarate Dehydrogenase
Ans:- Isocitrate dehydrogenase and -ketoglutarate dehydrogenase
explanation:- in citric acid cycle isocitrate dehydrogenase convert D-isocitrate into -ketoglutarate in presence of NAD+ and release first molecule of CO2. -ketoglutarate get converted into succinyl co-A in presence of enzyme -ketoglutarate dehydrogenase and NAD+. this reaction release another CO2 molecule in citric acid cycle. the reactions catalyse by other enzymes in citric acid cycle do not produce CO2.
