1. Which of the following statements is FALSE?
A. The amino acid pool is the body's total supply of amino acids in the body's proteins.
B. Fats and carbohydrates are oxidized directly to produce cellular energy.
C.Amino acids can be used to supply energy only after being converted to a citric acid cycle intermediate.
D. Excess carbohydrate and fat can be stored as such, whereas excess amino acids are oxidized for energy or converted to fat or glycogen for storage.
2. If you were to jog one kilometer a few hours after lunch, which stored fuel would you probably tap?
A. muscle proteins
B. blood proteins
C. fat stored in adipose tissue
D.liver glycogen and muscle glycogen
3.A fasting animal whose energy needs exceed those provided in its diet will draw on its stored resources in which order? (See slides 81-82 in the Exam 3 review PowerPoint.)
A.fat, then glycogen, then protein
B. glycogen, then protein, then fat
C. liver glycogen, then muscle glycogen, then fat
D. muscle glycogen, then fat, then liver glycogen

Ischemia is associated with an increase in concentrations of AMP. What role does AMP play in shifting energy production from oxidative metabolism to glycolysis? Please be specific and include any glycolytic enzyme(s) involved. Of note, AMP induces an enzyme AMP Kinase (AMPK) which is involved in metabolic alterations during ischemia. We will learn about AMPK in Lecture 11 and you are not expected to discuss it in this problem. Please discuss another role(s) that AMP plays. Please be brief.
