Question

Choose the correct combination of labelling the number of carbon compounds in the substrate molecules, involved in the citric acid cycle.

• A. (A)4C, (B)6C, (C)5C, (D)4C, (E)4C
• B. (A)6C, (B)5C, (C)4C, (D)3C, (E)2C
• C. (A)2C, (B)5C, (C)6C, (D)4C, (E)4C
• D. (A)4C, (B)6C, (C)6C, (D)4C, (E)5C
• E. (A)4C, (B)6C, (C)4C, (D)4C, (E)4C

Answer 1

The correct option is A (A)4C, (B)6C, (C)5C, (D)4C, (E)4C

Number of carbon compounds in the substrate molecules of citric acid cycle are:- oxalo acetic acid- 4 , citric acid- 6, alpha-ketoglutaric acid- 5, succinic acid- 4 and malic acid- 4.

So, the correct answer is '(A)4C, (B)6C, (C)5C, (D)4C, (E)4C'
