The sum of all chemical changes within an organism is known as . This complex network is divided into two primary pathways:

This pathway explains how the blueprint in our genes is eventually expressed as the functional molecules (proteins) that perform most cellular tasks. Essentials of Biochemistry

: These serve as the primary source of energy (e.g., glucose) and provide structural support in plants and microorganisms. The sum of all chemical changes within an

These reactions are almost always facilitated by , which accelerate chemical processes that would otherwise happen too slowly to sustain life. The "Central Dogma" These reactions are almost always facilitated by ,

Biochemistry is the scientific study of the chemical substances and vital processes that occur within living organisms. By bridging molecular biology and chemistry, this discipline provides a detailed map of life at its most fundamental level—from individual atoms to complex cellular systems.

The chemical makeup of life is surprisingly specialized. While the periodic table contains over 100 elements, roughly is composed of just six: carbon, hydrogen, oxygen, nitrogen, phosphorus, and calcium.

: The "workhorses" of the cell, proteins provide structure, regulate cellular processes, and act as organic catalysts known as enzymes.
