Explanation: 

Detailed explanation-1: -Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones.

Detailed explanation-2: -Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Detailed explanation-3: -Protein is in every cell in the body. Our bodies need protein from the foods we eat to build and maintain bones, muscles and skin. We get proteins in our diet from meat, dairy products, nuts, and certain grains and beans. Proteins from meat and other animal products are complete proteins.

Detailed explanation-4: -The information to produce a protein is encoded in the cell’s DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome. Ribosomes read the information in the mRNA and use that information to assemble amino acids into a protein.

Detailed explanation-5: -Proteins are essential for life and are essential for a wide range of cellular activities. Protein enzymes catalyze the vast majority of chemical reactions that occur in the cell. Proteins provide many of the structural elements of a cell, and they help to bind cells together into tissues.
