Question

Following an acute bout of endurance exercise training, the increase in mitochondrial biogenesis occurs within _____ following the completion of the exercise session.

a) minutes
b) hours
c) seconds
d) days

Answer 1

Mitochondrial biogenesis, a response to endurance exercise, begins within hours after the exercise session, improving energy production in muscle cells.

Step-by-step explanation:

The question relates to an exercise-induced physiological response known as mitochondrial biogenesis, which is the process by which new mitochondria are formed in the cell. Following an acute bout of endurance exercise, the increase in mitochondrial biogenesis occurs within hours following the completion of the exercise session. This process is essential for improving endurance as it enhances the ability of the muscle cells to produce energy. Mitochondria are often referred to as the powerhouse of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.
