arasympathetic signaling to β-cells involves the binding of ach to muscarinic receptors. these receptors are gpcrs that are coupled to a subfamily of g proteins which causes downstream elevations of ca2 in the cytoplasm. given this information, with which subfamily of g proteins must these gpcrs be coupling?

Respuesta :

An increase in lipolysis is one adaptation that results in higher HGP.these receptors are gpcrs that are coupled to a subfamily of g proteins which causes downstream elevations of ca2

Triacylglycerols (TAGs) hydrolyze into their constituent molecules, glycerol and free fatty acids, during the metabolic process known as lipolysis(FFAs). Adipose TAGs in the body are used to store fat, which is then used as insulation, energy, and heat. During periods of hunger, the body primarily draws energy from its fat reserves while preserving protein. Overall, fats are the body's most significant source of fuel, and how long a person can go without meals mostly relies on how much fat is stored in adipose tissue. Thus, when the body is in the fasting state of metabolism and blood glucose levels have dropped, lipolysis is particularly crucial. But it also happens in unstimulated (basic) conditions.
