Final answer:
Cortisol release during stress leads to the accumulation of adipose tissue and release of free fatty acids into the bloodstream, as part of the body's long-term stress response to maintain energy levels.
Step-by-step explanation:
The release of cortisol that results from stressful events can lead to an increase in the accumulation of adipose tissue & subsequently the release of free fatty acids into the blood stream. When the hypothalamus perceives stress, it triggers the anterior pituitary gland to release adrenocorticotropic hormone (ACTH), which in turn stimulates the release of glucocorticoids, like cortisol, from the adrenal cortex. These glucocorticoids promote the catabolism of stored nutrients, such as glycogen to glucose and triglycerides into free fatty acids and glycerol, increasing their levels in the blood. This process is part of the body's long-term stress response, which is essential in providing fuel for the body during prolonged periods of stress but can lead to harmful effects if the stress is chronic. These effects include the redistribution of fat to certain areas of the body and a weakened immune system.
