Outline the control of blood glucose.
A definition of normal glucose levels was expected, mentioning how it is regulated despite variable intake. Most answers incorporated the roles of insulin/glucagon and the glucostat function of the liver. Sufficient detail regarding the mechanism of insulin release was often lacking. Extra marks were awarded for description of the role of the satiety centre in the hypothalamus, glucokinase and processes in fasting and starvation that maintain blood glucose levels.
Marks were not awarded for describing effects of insulin and glucagon unrelated to glucose control.
