d
Acetoacetyl-CoA
QuestionChoice
This enzyme is responsible for the conversion of 3-hydroxy-3-methylglutaryl-CoA to mevalonate. This reaction is part of the cholesterol synthesis pathway.

b
3-hydroxyl-3-methylglutaryl CoA (HMG-CoA) reductase
QuestionChoice
This enzyme catalyses the reaction between acetoacetyl-CoA and acetyl-CoA to form 3-hydroxyl-3-methylglutaryl CoA (HMG-CoA).

e
3-hydroxyl-3-methylglutaryl CoA (HMG-CoA) synthase
QuestionChoice
Fatty acids are transported to the liver and activated by acyl-CoA synthase in the cytoplasm to form fatty acyl-CoA. Activation of the fatty acyl-CoA traps the fatty acid in the cell. In order for it to cross the mitochondrial membrane, it reacts with carnitine to form acyl-carnitine which passes into the mitochondria.

Fatty acids are broken down to release energy from reserves stored in adipose tissue. This involves mobilisation, activation and degradation.

Which of the following activates fatty acids in the liver?
a
