Adrenaline raises blood glucose by binding to receptors on target cells, triggering the breakdown of glycogen into glucose and the synthesis of glucose from other molecules, thereby increasing blood glucose levels.
- attaches to adrenaline receptor on surface of target cells - receptor activates adenylate cyclase enzyme - adenylate cyclase converts ATP into cyclic AMP - cAMP acts as a second messenger and activates protein kinase - protein kinase converts glycogen into glucose by glycogenolysis - protein kinase converts amino acids and glycerol into glucose by gluconeogenesis - maintains larger concentration gradient of glucose for - more facilitated diffusion of glucose out of the cell - increase in blood glucose concentration
