Which statement best defines inhibitors in enzyme regulation?

In enzyme regulation, inhibitors are molecules that decrease enzyme activity by binding to the enzyme. This binding can block the active site so substrates can’t bind, or it can occur at other sites and change the enzyme’s shape to reduce its catalytic efficiency. Whether the inhibition is reversible or irreversible, the overall effect is a slower reaction rate, providing cells a way to tune metabolic pathways in response to conditions. This matches the idea that inhibitors are naturally occurring molecules that bind to enzymes and slow reactions. Substrates drive activity by being converted, cofactors are required for catalysis but aren’t inhibitors, and products that speed up reactions don’t align with inhibition.
