BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-2: -Each polypeptide chain in such a protein is called a protein subunit. In the simplest case, two identical folded polypeptide chains bind to each other in a “head-to-head” arrangement, forming a symmetric complex of two protein subunits (a dimer) held together by interactions between two identical binding sites.

Detailed explanation-3: -True. Proteins are composed of amino acids.

Detailed explanation-4: -Amino acids are the building blocks of protein. Proteins are long chains of amino acids. Your body has thousands of different proteins that each have important jobs. Each protein has its own sequence of amino acids.

Detailed explanation-5: -Although their structures, like their functions, vary greatly, all proteins are made up of one or more chains of amino acids.
