Enzyme-coupled reactions

Enzyme-coupled reactions involve using one enzyme’s activity to drive another reaction forward, often by linking a less favorable reaction to a more favorable one. Essentially, the first enzyme catalyzes a reaction that produces a molecule used by the second enzyme to complete its reaction efficiently. This process helps control and accelerate complex biological pathways, ensuring cells perform necessary functions smoothly. Think of it like using a small initial action to power a bigger, important task, with enzymes acting as biological catalysts that speed up reactions without being consumed.
