Expert Solution
Step 1: Proteins

Proteins are intricate molecules that are necessary for all living things to function. They consist of chains of amino acids that have been folded into distinct three-dimensional structures.

A protein's tertiary structure, or three-dimensional structure establishes the locations of binding and active sites, proteins can perform a wide range of functions in cells and organisms. It also determines how a protein interacts with other molecules and carries out particular biological tasks.
