1.a. When an enzyme is denatured, its specific three-dimensional structure, including the active site, is disrupted. This structural change causes the enzyme to lose its ability to bind to its substrate and catalyze the reaction, rendering it inactive and non-functional.
1.b. Four factors that alter the rate of enzyme-catalyzed reactions are:
Temperature
pH
Enzyme concentration
Substrate concentration
1.c. Enzyme inhibition kinetics is fundamental in drug design because many drugs function by inhibiting specific enzymes involved in disease processes. By studying how an inhibitor binds to an enzyme and affects its activity (e.g., competitive, non-competitive, uncompetitive inhibition), researchers can design more potent and selective drugs. For example, statins are a class of drugs designed to lower cholesterol by competitively inhibiting the enzyme HMG-CoA reductase, a key enzyme in cholesterol biosynthesis. Understanding the kinetics allows for the optimization of drug dosage and minimizes off-target effects.
