Fast-twitch muscle cells rely heavily on anaerobic respiration for their ATP production, whereas slow-twitch muscle cells rely on aerobic respiration. Considering this information, which of the following is true?

a. As compared to fast-twitch muscle cells, slow-twitch muscle cells produce a ATP more quickly.
b. As compared to slow-twitch muscle cells, fast-twitch muscle cells produce a higher ATP yield per glucose molecule.
c. Fast-twitch muscle cells have a poor blood supply compared to slow-twitch muscle fibers.
d. Fast-twitch muscle cells require oxygen for ATP production, whereas slow-twitch muscle cells primarily metabolize glucose in the absence of oxygen.


Answer: c. Fast-twitch muscle cells have a poor blood supply compared to slow-twitch muscle fibers.
