The correct order for these three processes leading from a fatty acid molecule in a cell needing energy to high energy molecules capable of meeting the energy need is
I.activation by reaction with coenzyme A
II.oxidation to acetyl-SCoA and reduced coenzymes
III.transport from cytosol into mitochondrial matrix

Question

Quizplus · Accepted Answer

The correct order is activation by reaction with coenzyme A (I), then transport from cytosol into mitochondrial matrix (III), and then oxidation to acetyl-SCoA and reduced coenzymes (II). This is because the fatty acid molecule needs to be activated by coenzyme A before it can be transported across the mitochondrial membrane, where it undergoes oxidation to produce acetyl-SCoA and reduced coenzymes. Therefore, the correct order is I, III, II, which corresponds to choice D.
