What process describes the movement of molecules from areas of high concentration to areas of low concentration

This is known as diffusion.

Molecules will move from areas of high concentration to areas of low concentration in order to form and maintain equilibrium. This process is passive and does not require the input of energy or ATP.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
