Problem:

Please read all the questions carefully and answer them.

Question 1: From a physiological point of view, starvation is merely prolonged food deprivation. Energy demands within post-absorptive animals are met by different means through time. Which process serves to minimize CNS glucose consumption during the early and middle phases of starvation?

(a) gluconeogenesis,

(b) ketogenesis,

(c) glycogenolysis, or

(d) proteolysis.

Question 2: What advantage do ketone bodies afford during the early and middle phases of starvation?

(a) small molecular weight,

(b) water-solubility,

(c) diffusion through the blood-brain barrier, or

(d) all of the above.

Question 3: Where does ketogenesis occur?

(a) adipose tissue found throughout the body,

(b) within the liver, or

(c) throughout skeletal muscle.

Question 4: Do animals have the ability to convert fatty acids into glucose?

(a) yes, or (b) no.

Question 5: Which energy reserve becomes depleted during the early phase of starvation?

(a) muscle glycogen,

(b) hepatic glycogen, or

(c) adipocyte triglyceride.
