Exercise 10

Explain how free fatty acid mobilization from the adipose cell decreases during maximal work in spite of the cell being stimulated by all the hormones to break down triglycerides.

Step 1 of 2

The muscles need excess of energy during exercise. To some extent, this is met with glucose. However, the glucose reserves in the body are limited, and the body needs to supply the fuel for all other parts also. Therefore, alternate fuels need to be mobilized to the muscles to meet the energy needs. Several hormones are involved in mobilization of free fatty acids from adipose tissue to spare carbohydrate. The hormones involved are glucagon, growth hormone, cortisol, epinephrine, and norepinephrine.
