Question

Regular aerobic exercise training affects carbohydrate (CHO) usage by ____. Select one: 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

Answer 1

B, increasing the number and size of mitochondria

Step-by-step explanation:

Answer 2

Option B, increasing the number and size of mitochondria

Step-by-step explanation:

Mitochondria (power house of a cell) produce energy. When no exercise is done, the productivity of mitochondria reduces but it increases with regular exercise. In fact aerobic training helps mitochondria in making more energy by enhancing its efficiency. With one cycle of exercise, mitochondria produce 32 ATPs. Aerobic exercise allows more of oxygen to get to the muscle cells, the faster it happens the more energy is produced

Hence, option B is correct
