The secretion of glucagon is regulated by: A) The hypothalamus B) Blood glucose levels C) The thyroid D) Variations in blood pH E) Adrenaline levels

Another hormone involved in the control of plasma glucose concentration is glucagon. Explain how glucagon increases blood glucose concentration.

What is glucagon? The hormone that stimulates the conversion of glucose to glycogenThe sugar used in respirationThe hormone that stimulates the breakdown of glycogen to glucoseThe storage carbohydrate found in liver and muscles

Which one of the following statements regarding glucagon is TRUE?Question 20Select one:a.Glucagon generally works in opposition to insulin in order to decrease blood glucose levelsb.Glucagon generally works in opposition to insulin so only one hormone (glucagon or insulin) is present in the bloodstream at any one time.c.Glucagon receptors are activated by epinephrine to trigger a cell signalling cascade and stimulate fatty acid release from storaged.Glucagon and insulin are both stimulated by increased amino acids in the bloodstream.e.Both a and d are TRUE.

Glucagon causesGroup of answer choicesAn increase in glucose utilisation and storagean increase in fatty acid synthesis and lipid storageAn increase in glycogen synthesisAn increase in blood glucose concentration

How does glucagon increase blood glucose levels?Group of answer choicesBy activating glycogen synthaseBy activating glycogen phosphorylaseBy activating pyruvate kinaseBy activating PFK-1
