Question

Brief description of biological importance of proteins

Answer 1

They are coded for by our genes and form the basis of living tissues. They also play a central role in biological processes. For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.

Answer 2

Hello dear ☺️

Here's the answer ⤵️

▶️ Biological importance of proteins:

✨i. Proteins are the essence of life processes.

✨ii. They are the fundamental constituents of all protoplasm and are involved in the struc­ture of the living cell and in its function.

✨iii. Enzymes are made up of proteins.

✨iv. Many of the hormones are proteins.

✨v. The cement substances and the reticulum which bind or hold the cells as tissues or organs are made up partly of proteins.

✨vi. They execute their activities in the trans­port of oxygen and carbon dioxide by hemoglobin and special enzymes in the red cells.

✨vii. They function in the homostatic control of the volume of the circulating blood and that of the interstitial fluids through the plasma proteins.

✨viii. They are involved in blood clotting through thrombin, fibrinogen and other protein factors.

✨ix. They act as the defence against infections by means of protein antibodies.

✨x. They perform hereditary transmission by nucleoproteins of the cell nucleus.
