Detailed explanation-1: -Thus, an additional and important action of adrenaline is to increase plasma glucose by promoting glycogenolysis in the liver and skeletal muscle, liver gluconeogenesis and reduction of glucose uptake by tissues such as skeletal muscle via activation of 1‐ and 2‐adrenoceptors (Moratinos et al., 1986).
Detailed explanation-2: -Your body uses glucose as its main fuel. The brain requires a constant supply of blood glucose and will signal the adrenal glands to release two hormones called adrenaline and cortisol whenever blood glucose levels are low.
Detailed explanation-3: -Abstract. In humans, adrenaline stimulates lipolysis, ketogenesis, thermogenesis and glycolysis and raises plasma glucose concentrations by stimulating both glycogenolysis and gluconeogenesis.
Detailed explanation-4: -Adrenaline is known to increase glycogen phosphorylase activity via cAMP activation of phosphorylase kinase and this may enhance glycogen breakdown during muscle contraction (Richter et al.
