Maintenance of optimal cell functioning requires a balanced cellular environment called

Homeostasis

Explanation:

Homeostasis is a property of organisms that consists in their ability to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the outside (metabolism). It is a form of dynamic equilibrium that is made possible thanks to a network of feedback control systems that constitute the self-regulation mechanisms of living beings.

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.
