Question

Which one of the following is not the function of insulin?
(A) Initiates the conversion of glycogen to glucose
(B) Initiates the formation of hepatic glycogen from the excess of glucose
(C) Increases the permeability of the cell membrane to glucose
(D) Increases the oxidation of glucose in the cells

Answer 1

Hint: Insulin is a type of hormone that helps in glucose uptake, glycogenesis, lipogenesis, and also the protein synthesis of skeletal muscle and fat tissue through the tyrosine kinase receptor pathway.

Complete step by step answer:
The function which was not performed by the insulin is to Initiate the conversion of glycogen to glucose. Insulin helps in glycogenesis, it is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage.

Additional Information: Insulin is a peptide hormone that was produced by the beta cells of the pancreatic islets. It is considered to be the most anabolic hormone of the body. It regulates the metabolism of many molecules like carbohydrates, fats, and protein by promoting the absorption of glucose from the blood into the organ liver, fat molecules, and striated muscle cells. In these types of tissues, the absorbed glucose is usually converted into two types i.e either glycogen via glycogenesis or to the fats (triglycerides) via the process of lipogenesis, or, as it was seen in the case of the liver. In the liver, it is converted into both. insulin inhibits the secretion and production of glucose by the liver within the blood. Circulating insulin also affects the synthesis of proteins during a wide range of tissues. Insulin helps in converting the small molecules into large molecules in the blood and cells and thus called an anabolic hormone. Low insulin levels if present within the blood has the other effect by promoting widespread catabolism, especially of reserve body fat.
So, the correct answer is ‘Initiates the conversion of glycogen to glucose’.

Note: Many people who are suffering from diabetes have to use insulin by themselves by injecting it with a syringe. the skin of the syringe is marked with lines denoting the quantity of medication within the needle. There are different size syringes that you simply can choose between with the assistance of your doctor.
