Given below are four respiratory enzymes. Arrange them in the decreasing order of number of carbon atoms present in the substrates they act on.
(A). Fumarase
(B). Aconitase
(C). Enolase
(D). - keto glutarate dehydrogenase
Choose the correct answer from the options given below:
(A). Fumarase
(B). Aconitase
(C). Enolase
(D). - keto glutarate dehydrogenase
Choose the correct answer from the options given below:
Options
- A(A), (B), (C), (D).
- B(B), (D), (A), (C).
- C(B), (A), (D), (C).
- D(C), (B), (D), (A).
Correct answer
B. (B), (D), (A), (C).
Step-by-step solution
Aconitase acts on citrate, which is a 6-carbon compound.
-ketoglutarate dehydrogenase acts on -ketoglutarate, which is a 5-carbon compound.
Fumarase acts on fumarate, which is a 4-carbon compound.
Enolase acts on 2-phosphoglycerate, which is a 3-carbon compound.
The decreasing order of the number of carbon atoms in their substrates is 6C, 5C, 4C, 3C.
This corresponds to the sequence (B), (D), (A), (C).
Answer: (B), (D), (A), (C).
-ketoglutarate dehydrogenase acts on -ketoglutarate, which is a 5-carbon compound.
Fumarase acts on fumarate, which is a 4-carbon compound.
Enolase acts on 2-phosphoglycerate, which is a 3-carbon compound.
The decreasing order of the number of carbon atoms in their substrates is 6C, 5C, 4C, 3C.
This corresponds to the sequence (B), (D), (A), (C).
Answer: (B), (D), (A), (C).
