BCHM 355/455: Biochemistry
Biochemical processes sustain life by driving molecular interactions, enzyme activity, and metabolic pathways. Water chemistry, amino acids, and protein structure determine biological function, while enzyme catalysis and thermodynamics regulate energy flow. Metabolic pathways and allosteric control maintain cellular balance.
