BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer and Explanation: The answer is A) proteins. This is because amino acids are known as the building blocks of protein. A sequence of amino acids can form the simplest protein structure called the primary structure, which is also known as a polypeptide chain.

Detailed explanation-2: -Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

Detailed explanation-3: -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.
