Question

Oxidative degradation of fatty acids results in production of _______, while the fatty acid biosynthesis pathways use ________ as the substrate for hydrocarbon chain-extending reaction by 3-Ketoacyl ACP synthase.

Select one:

a. acetyl CoA ;;; malonyl CoA

b. malonyl CoA ;;; acetyl CoA

c. acetyl CoA ;;; acetyl CoA

d. malonyl CoA ;;; malonyl CoA

e. None of these

Answer 1

The correct option is-

c. acetyl CoA ;;; acetyl CoA

In mitochondria, Oxidative degradation of fatty acids occurs when fatty acid breaks down to acetyl coA. It undergoes a series of oxidation and hydration reactions.

In fatty acid biosynthesis, malonyl ACP is condensed to form acetoacyl ACP with the help of 3-Ketoacyl ACP synthase. Then it undergoes hydrocarbon chain-extending reactions to form various ACPs.
