Question

Four respiratory enzymes are given below. Arrange them in increasing order of the carbon number in the substrates on which they act. 1. Enolase 2. Aconitase 3. Fumarase 4. Alcohol dehydrogenase

TestHub · Accepted Answer

Enolase works on 2-phosphoglyceric acid (3C-compound), aconitase on citric acid (6C-compound), fumarase on fumaric acid (4C-compound) and alcohol dehydrogenase on acetaldehyde (2C-compound). Thus, the ascending order of these enzymes based on the carbon number of the substrates on which they act is: IV, I, III, II (alcohol dehydrogenase, enolase, fumarase and aconitase).
