Slow fibers primarily use which of the following substrates for energy?

Question

Quizplus · Accepted Answer

Slow fibers (also known as type I fibers) primarily use aerobic metabolism for energy production. This means they can use carbohydrates, fats, and even amino acids as substrates for energy through the oxidative pathway. Glycogen and anaerobic metabolism are primarily used by fast-twitch fibers, while protein is not a preferred substrate for energy production during exercise.
