Concept explainers
Interpretation: To determine the molecule that shuttles activated fatty acid molecules across the inner mitochondrial membrane.
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.
The first stage of fatty acid oxidation is the activation of fatty acids in the outer mitochondrial membrane. The fatty acid is activated by
