Which neurotransmitter is also known as adrenaline and impacts glucose metabolism and energy release during exercise?

Epinephrine, commonly known as adrenaline, plays a critical role in the body's response to stressors, particularly during physical exertion such as exercise. It is produced by the adrenal glands and is part of the body's fight-or-flight response. When released into the bloodstream, epinephrine increases heart rate, elevates blood pressure, and boosts energy supplies by promoting glucose metabolism. This leads to the breakdown of glycogen into glucose, which provides an immediate source of energy for muscle cells during strenuous activity.

Additionally, epinephrine affects various bodily functions, enhancing the capacity for quick responses during situations that require immediate physical effort. This is essential for athletes or individuals engaging in high-intensity exercise, as it supports increased energy availability and improves overall performance. The role of epinephrine in metabolic processes and energy release during exercise directly correlates with its significance in physiology and its classification as adrenaline.
