Concept explainers
(a)
Interpretation:
In the context of fatty acid oxidation to acetyl CoA whether acyl carnitine is involved in (1) fatty acid activation, (2) fatty acid transport, or (3) β-oxidation pathway has to be identified.
Concept introduction:
Fatty acids are molecules that are long hydrocarbon chain of
The fatty acids are broken down to provide energy. The breakdown of fatty acids is a three parts process. In the first part, the fatty acid is activated. In the second part, the transportation of fatty acid into the mitochondrial matrix is facilitated by a shuttle mechanism. In the third part, the fatty acid is readily oxidized, cycling through a series of four reactions. In these series of reactions, acyl CoA is degraded to acetyl CoA. This pathway is termed as a β-oxidation pathway. Acetyl CoA, FADH2, and NADH are produced in this reaction.
(b)
Interpretation:
In the context of fatty acid oxidation to acetyl CoA whether enoyl CoA is involved in (1) fatty acid activation, (2) fatty acid transport, or (3) β-oxidation pathway has to be identified.
Concept introduction:
Fatty acids are molecules that are long hydrocarbon chain of carboxylic acid. They are building blocks of fat in humans and animals.
