Discuss how hormones regulate metabolism and can change during exercise. Detail their stimulus, effects and mechanisms of action.
Understand the Problem
The question is asking for a detailed discussion on the role of hormones in regulating metabolism, particularly how their levels and effects change during exercise. It specifically requests information on the stimulus for hormone release, their effects on metabolism, and the mechanisms by which they act within the body.
Answer
Hormones such as adrenaline and cortisol regulate metabolism by influencing energy use during exercise. They are triggered by stress and increase fuel availability.
Hormones like adrenaline, noradrenaline, cortisol, and growth hormone regulate metabolism by influencing energy utilization and storage. During exercise, these hormones are released in response to stress and increase the availability of fuels like glucose. They achieve these effects through mechanisms such as receptor activation and subsequent cellular responses.

Hormones like adrenaline, noradrenaline, cortisol, and growth hormone regulate metabolism by influencing energy utilization and storage. During exercise, these hormones are released in response to stress and increase the availability of fuels like glucose. They achieve these effects through mechanisms such as receptor activation and subsequent cellular responses.
More Information
Hormones play a critical role in metabolizing energy. For instance, during exercise, adrenaline increases heart rate and blood flow, while glucagon increases glucose in the bloodstream. Growth hormone increases protein synthesis, which is crucial for tissue repair.
Tips
One common mistake is assuming that all hormones decrease during exercise. Some actually increase to meet the energy demands of the body.
