Ketone bodies are formed as a result of the breakdown of fatty acids and certain ketogenic amino acids. The formation of ketone bodies is called ketogenesis. The three ketone bodies produced are acetoacetate, beta-hydroxybutyrate and acetone. At the time of starvation, more ketone bodies are produced. The accumulation of ketone bodies may lead to ketoacidosis.
1. Ketogenesis is preferred under which of the following conditions?
(a) When glucose supply is high
(b) When glucose supply is less
(c) When glucose supply is constant
(d) None
Answer: (b)
