Adrenaline interacts with target cells through a multi-step process that involves binding to receptors, activating a second messenger system, and leading to the phosphorylation and activation/inhibition of enzymes, which ultimately increases glucose availability for energy production.
Adrenaline, also known as epinephrine, is a hormone that plays a vital role in the control of blood glucose during fight-or-flight situations. When adrenaline binds to the beta-adrenergic receptors on muscle cells, it triggers a cascade of events inside the cell.
The result is an increase in glucose available for the muscle cell, which is essential for responding to the sudden surge of energy required during emergent situations. This mechanism shows how adrenaline acts through a second messenger system to bring about a fast and efficient response in target cells for energy production. Below is the flow diagram attached
