1 Answer

Answer :

Step 1: Absence of insulin leads to excessive hydrolysis of triacyl glycerol. Step 2: So more fatty acid is available, and more acetyl CoA is produced. Step 3: But oxidation of acetyl CoA in citric acid cycle is sluggish. The excess acetyl CoA is diverted into ketone body formation.
