biochemical basis of life
The biochemical basis of life refers to the chemical processes that sustain living organisms. At its core, life depends on molecules like proteins, lipids, carbohydrates, and nucleic acids, which perform essential functions. Proteins act as enzymes and structural components; nucleic acids store genetic information; lipids form cell membranes; and carbohydrates provide energy. These molecules interact through complex chemical reactions, enabling growth, reproduction, energy conversion, and response to the environment. Understanding these biochemical processes helps explain how living things maintain their structure, function, and continuity at a molecular level.
