Question

The protein which maintains blood sugar level in the human body
(A) Haemoglobin
(B) Oxytocin
(C) Insulin
(D) Ptyalin

Answer 1

Hint : Proteins are organic molecules that are present in living organisms. They serve a wide range of functions including organization, transportation, and defence. Protein has only a small effect on blood glucose levels. Protein tends to help stabilize blood sugars by blunting the absorption of carbohydrates/sugars.

Complete Step By Step Answer:
Haemoglobin is a protein found in the red blood cells. These cells are responsible for carrying oxygen around the body. In addition to transporting oxygen, haemoglobin carries carbon dioxide out of the cells and into the lungs.
Oxytocin is a hormone that acts on organs in the human body and is a chemical messenger in the brain, controlling key aspects of the reproductive system, including childbirth and lactation, and aspects of human behaviour.
Saliva contains the enzyme amylase, also called ptyalin. Ptyalin is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine.
Insulin hormone is secreted by the pancreas. Insulin helps control blood glucose levels by signalling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
Hence, the correct Option is C. Insulin.

Note :
Protein is made up of long chains of amino acids. There are 20 amino acids. The specific order of amino acids determines the structure and function of each protein. Protein breaks down into glucose more slowly than carbohydrates.
