Why is there a difference between the amount of ATP produced by glucose and by glycogen?
a. The breakdown of glycogen requires many more steps thus more ATP is produced along the way.
b. The breakdown of glycogen requires less ATP in the energy investment phase.
c. Glucose and glycogen use very different metabolic pathways to yield pyruvate and that accounts for the difference in ATP production.
d. Less water is produced when glucose is the starting compound and that directly affects ATP production.
Q. 2Which factor increases resting metabolic rate by an estimated 15-25 percent?
A) cigarette smoking
B) caffeine
C) environmental temperature
D) ascending to high altitudes
Q. 3Why does the amount of ATP produced in skeletal muscle differ from the amount produced in other tissues?
a. Skeletal muscle is more efficient than other tissues in the production of ATP.
b. Skeletal muscle transfers electrons via FAD while other tissues use NAD.
c. Skeletal muscle completely oxidizes carbohydrates while other tissues do not.
d. Skeletal muscle has fewer rate-limiting enzymes than do other tissues.
