Question 1

Which enzyme adds on a CoA to a fatty acid? What does this do?

Answer 1

Fatty acyl CoA synthase, activates fatty acid

Question 2

What happens if a FA has an odd no of carbons?

Answer 2

Oxidised until it forms Malonyl CoA, then converted to succinyl CoA

Question 3

What is the carnitine shuttle inhibited by?

Answer 3

Malonyl CoA

Question 4

Describe steps of carnitine shuttle

Answer 4

Fatty acyl CoA loses CoA, fatty acyl added to carnitine, fatty acyl carnitine transported across inner membrane, fatty acyl removed, rejoined to CoA, carnitine transported back across membrane.

Question 5

What is B oxidation of fatty acids?

Answer 5

Addition of a CoA enzyme, transport across inner mitochondrial membrane via carnitine shuttle, cleavage of 2 carbons to produce Acetyl CoA
