Final answer:
The statement is true; glucose-elevating agents decrease insulin release and accelerate glycogen breakdown, through a process called glycogenolysis, to increase blood glucose levels.
Step-by-step explanation:
The statement given is true. The role of glucose-elevating agents indeed involves a decrease in insulin release and the acceleration of glycogen breakdown in the liver, a process known as glycogenolysis. When blood glucose levels fall, the alpha cells in the pancreas release glucagon, which stimulates the liver to convert glycogen into glucose, ultimately increasing blood glucose levels.
After a meal, when blood glucose levels are high, beta cells in the pancreas release insulin to stimulate the conversion of glucose into glycogen, thus reducing blood glucose levels. However, when the body needs more glucose, such as between meals or during exercise, glucagon is released to induce glycogenolysis and also gluconeogenesis, which is the synthesis of glucose from non-carbohydrate sources to maintain glucose levels within the normal range.
