Detailed explanation-1: -An enzyme inhibitor stops ("inhibits") this process, either by binding to the enzyme’s active site (thus preventing the substrate itself from binding) or by binding to another site on the enzyme such that the enzyme’s catalysis of the reaction is blocked. Enzyme inhibitors may bind reversibly or irreversibly.

Detailed explanation-2: -Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.

Detailed explanation-3: -Mercury and other toxic heavy metals disrupt cellular function by inhibiting or denaturing critical enzymes and proteins.

Detailed explanation-4: -The results indicated that lead is a potent but somewhat selective inhibitor of enzyme synthesis in soil, and that highly insoluble lead compounds, such as PbS, may be potent modifiers of soil biological activity.

Detailed explanation-5: -Enzyme inhibitors are substances which alter the catalytic action of the enzyme and consequently slow down, or in some cases, stop catalysis. There are three common types of enzyme inhibition-competitive, non-competitive and substrate inhibition.
