Regular aerobic exercise training affects carbohydrate (CHO) usage by ____.
A) increasing the enzymatic activity associated with glycolysis
B) increasing the number and size of mitochondria
C) decreasing liver glycogen storage so more CHO is stored as muscle glycogen
D) decreasing the oxidative capacity of muscle

Question

Quizplus · Accepted Answer

Regular aerobic exercise training increases the number and size of mitochondria in muscle cells. Mitochondria are responsible for producing energy through the breakdown of carbohydrates, fats, and proteins. An increase in the number and size of mitochondria leads to an increase in the oxidative capacity of the cell, allowing for more efficient carbohydrate usage.
