BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are broken down into amino acids, also called their building blocks. They are essential for all cells to build new proteins.

Detailed explanation-2: -Some proteins, it turns out, can make other proteins. Proteins are assembled from amino acids inside cellular structures called ribosomes.

Detailed explanation-3: -Answer and Explanation: Answer (a) is false. Proteins tend to fold into 3-dimensional shapes.

Detailed explanation-4: -A:True. Proteins are essential components of our cells, tissues, and organs. Proteins are large molecules with complex structures. Each of the enzymes in our cells are proteins that have specialized functions in the operations of the cells.

Detailed explanation-5: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
