Final answer:
Cortisol is the hormone that plays a crucial role in ensuring that more glucose is available for fuel in the bloodstream by promoting glycogenolysis and gluconeogenesis.
Step-by-step explanation:
Cortisol is a glucocorticoid hormone that plays a key role in regulating blood glucose levels, especially during times of stress. It increases the availability of glucose in the bloodstream by promoting the breakdown of glycogen into glucose in the liver, a process known as glycogenolysis. Moreover, cortisol supports the process of gluconeogenesis, which is the production of new glucose from non-carbohydrate sources in the liver. It also promotes the release of fatty acids from adipose tissue. The release of cortisol is triggered by Adrenocorticotropic hormone (ACTH) from the pituitary gland, and its levels are managed through a negative feedback mechanism.
Cortisol plays an important role in ensuring that more glucose is available for fuel in the bloodstream. It is a glucocorticoid that stimulates the synthesis of glucose and gluconeogenesis by liver cells. Cortisol increases blood glucose levels to maintain them within a normal range between meals.
