AP Biology Unit 1: Chemistry of Life

Unit 1: Chemistry of Life: The Molecular Foundations of Biology Life is chemistry. Every cellular process — from DNA replication to muscle contraction — is fundamentally a set of chemical reactions governed by the properties of atoms and molecules. Unit 1 establishes the chemical vocabulary and conceptual toolkit you will rely on throughout AP Biology. Master this unit thoroughly, because every subsequent unit (cell structure, energetics, genetics, evolution, ecology) builds directly on these molecular foundations. --- 1.
