Enzyme catalysis inside cells falls into three groups: coenzyme-dependent redox reactions, metabolite transformations, and reversible covalent modifications. This video covers each group, from NAD+ and FAD redox chemistry to isomerization, hydrolysis, and regulatory phosphorylation and methylation.

Key concepts covered: coenzyme-dependent redox reactions, NAD+/NADH and FAD/FADH2, isomerization, condensation, hydrolysis and dehydration, reversible covalent modification, kinases and phosphatases, DNA methylation.
