If given the exact same amount of ATP,which of the three fiber types would be able to contract for the longest amount of time?
A) slow oxidative fibers
B) fast glycolytic fibers
C) both fast glycolytic and fast oxidative fibers
D) fast oxidative fibers

Question

Quizplus · Accepted Answer

Slow oxidative fibers utilize aerobic metabolism to produce ATP, which is more efficient and produces more ATP per molecule of glucose compared to anaerobic metabolism used by fast glycolytic fibers. Therefore, slow oxidative fibers can contract for longer periods of time with the same amount of ATP. Fast glycolytic fibers can only rely on anaerobic metabolism, which produces lactic acid and fatigue quickly. Fast oxidative fibers can use both aerobic and anaerobic metabolism, but still not as efficiently as slow oxidative fibers.
