Multiple Choice

Which of the following are characteristics of oxidative muscle fibers?

High myoglobin content and many mitochondria

Low myoglobin content and few mitochondria

Primarily anaerobic metabolism and high glycogen stores

Fast contraction speed and low fatigue resistance

Previous problemNext problem

Verified step by step guidance

Understand that oxidative muscle fibers are specialized for endurance and sustained activities, which require efficient oxygen use.

Recognize that high myoglobin content is a characteristic of oxidative fibers because myoglobin helps store and transport oxygen within muscle cells.

Identify that many mitochondria are present in oxidative fibers to support aerobic respiration, which is the process of producing ATP using oxygen.

Note that oxidative fibers primarily rely on aerobic metabolism, not anaerobic, which means they do not have high glycogen stores as a primary energy source.

Acknowledge that oxidative fibers typically have a slower contraction speed but high fatigue resistance, allowing them to sustain activity over long periods.
