The smaller molecules make up amino acids
Amino acids form the building blocks of proteins. RNA (three kinds) actually do the building.

Amino acids make up proteins.
Amino acids form proteins.
Enzymes are the special proteins that can break down large molecules into smaller molecules. These biological catalysts speed up chemical reactions in cells by lowering the activation energy required for the reaction to occur.
Proteins are formed from aminoacids.
Small organic molecules that are linked together make up macromolecules such as proteins, carbohydrates, and nucleic acids. These macromolecules are essential for various biological processes in living organisms.
PUMPS (proteins) pump molecules in and out of the cell by using energy
Small molecules that must combine with large proteins to become immunogenic are called haptens. Haptens alone are not immunogenic, but when they bind to proteins in the body, they can elicit an immune response.
There is no "site". Import and export of molecules is regulated by receptor proteins and the concentrations of these proteins. Concentration gradient is also important for small molecules.
Channel proteins are on the plasma membrane, selectively transport the solutes such as ions, small and large proteins across the membrane. Carrier proteins also membrane proteins that allow diffusion of different molecules. Both proteins are chemically made up of amino acids.
Food passes from the Mouth to the Pharynx to the Esophagus and then to the stomach, where gastric juices break up proteins and other molecules. From the Stomach, food passes to the Small intestine, where nutrients are absorbed into the body`s bloodstream. Creative Biogene
