Addition of more myoglobin to a muscle fiber would have the largest effect on __________.

Question

Quizplus · Accepted Answer

Myoglobin enhances the oxygen supply within muscle fibers, which is particularly beneficial for oxidative metabolism. Fast oxidative and slow oxidative fibers rely heavily on aerobic metabolism, making them the most affected by increased myoglobin, which improves their efficiency in using oxygen. Fast glycolytic fibers primarily use anaerobic metabolism and would benefit less from additional myoglobin.
