Question

Which of the following statements is true?

1-Insulin is produced by the beta pancreatic cells

2-All of these are true

3-Insulin acts as an enzyme in the conversion of glucose to glycogen

4-Insulin stimulates gluconeogenesis

Answer 1

Answer is 1) insulin is produced by beta cells of pancreas

Pancreas has two types of tissues - endocrine pancreas producing hormones and exocrine pancreas producing enzymes and ions etc.

Insulin is a hormone formed by beta cells of pancreas which is responsible for uptake of glucose from blood to the the liver cells, fats cells and muscle cells. It is a hypoglycemic hormone which is released after meals to increase uptake of sugar by tissues.

It stores glucose in the form of major storage form glycogen by the process known as glycogenesis. It is an anabolic hormone.

Glucagon is a hormone released by alpha cells of pancreas, which has opposite role to insulin. It increases release of glucose in blood by glycogenolysis and gluconeogenesis. It is a hyperglycemic hormone which is released in response to low blood sugar levels. It is a catabolic hormone.
