Carbohydrates are essential macromolecules that are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
Fats and oils, which may be saturated or unsaturated, can be unhealthy but also serve important functions for plants and animals.
DNA is a nucleic acid that controls all cellular activities, while RNA creates the proteins that makes these events occur.
An amino acid contains an amino group, a carboxyl group, and an R group and combines with other amino acids to form polypeptide chains.
Proteins perform many essential physiological functions, including catalyzing biochemical reactions.
Cells couple the exergonic reaction of ATP hydrolysis with endergonic reactions to harness the energy within the bonds of ATP.
