Even reactions that release energy (exergonic) require a "push" of activation energy to get started. Enzymes lower this barrier.

Proteins are the workhorses of the cell. Made of chains of , they serve as structural components, molecular transporters, and—most importantly— enzymes . Enzymes are biological catalysts that speed up chemical reactions by millions of times, allowing life to persist at room temperature. Nucleic Acids (DNA and RNA) Fundamentals of Biochemistry

Nucleic acids—DNA (deoxyribonucleic acid) and RNA (ribonucleic acid)—are the molecules of heredity. Even reactions that release energy (exergonic) require a
