Beta-adrenergic receptors

Beta-adrenergic receptors are proteins found on the surfaces of many cells in the body. They play a crucial role in the body's response to stress and regulation of functions like heart rate, airways, and energy metabolism. When hormones like adrenaline bind to these receptors, they trigger various responses: increasing heart rate, relaxing muscles in the airways, and mobilizing energy stores. This is part of the "fight or flight" response, helping the body react to stressful situations. Medications targeting these receptors can be used to treat conditions like asthma and high blood pressure.
