(b) Insulin, glucagon and adrenaline
Three important hormones right there. As with everything in our wonderful bodies, it is a precise balancing act that we need to respect, taking good care of our health and not putting them under more pressure than needed. And when regular balance doesn't cut it, adrenaline kicks in to over-ride, making sure we have the ATP-generating capacity to cope with most things life throws at us.

The diagrams below show the location of the pancreas and liver within the human body and also highlight the role of insulin and glucagon when blood glucose concentrations increase and decrease, respectively.
The diagrams below show the location of the pancreas and liver within the human body and also highlight the role of insulin and glucagon when blood glucose concentrations increase and decrease, respectively.
Pancreatic receptors respond to raised blood glucose levels by increasing secretion of insulin from the pancreas. Insulin activates the conversion of glucose to glycogen in the liver, decreasing blood glucose concentration.
Pancreatic receptors respond to lowered blood glucose levels by increasing secretion of glucagon from the pancreas. Glucagon activates the conversion of glycogen to glucose in the liver increasing the blood glucose concentration.
