Question

What are the two functions of protein?

Answer 1

Proteins:

Proteins are complex macromolecules that are made up of a long chain of amino acids, they play multiple functions in the body and are building blocks of the body.

Two functions of proteins:

1. Provide structure:

1. Proteins are required for the maintenance and structure of tissues.
2. Some proteins are fibrous and offer cells and tissues stiffness and rigidity.
3. These proteins encompass keratin, collagen, and elastin, which assist shape the connective framework of structures in the body.
4. Keratin is a structural protein that is determined on your skin, hair, and nails.
5. Collagen is the maximum amount of protein in the body and is the structural protein of your bones, tendons, ligaments, and skin.
6. Elastin is numerous instances extra flexible than collagen.
7. Its excessive elasticity permits many tissues on your frame to go back to their authentic form after stretching or contracting, consisting of your uterus, lungs, and arteries.

2. Enzymatic function:

1. Enzymes are proteins that support thousands of biochemical reactions that occur inside and outside cells.
2. The structure of the enzyme allows it to bind to other intracellular molecules called substrates, catalyzing reactions essential for metabolism.
3. Enzymes can also function outside the cell-like digestive enzymes such as lactase and sucrase help digest sugar.
4. Some enzymes require other molecules, such as vitamins and minerals, for the reaction to take place.
