If another molecule, having a shape very similar to the enzymes substrate, binds to its active site, it would then _ the enzyme's function.
Correct answer: B. Inhibit
- A. Fasten
- B. Inhibit
- C. Reverse
- D. Decrease
Explanation
If another molecule, having a shape very similar to the enzyme's substrate, binds to its active site, it would then inhibit the enzyme's function. This type of inhibition is known as competitive inhibition. The molecule that is similar in shape to the substrate is called the competitive inhibitor. By binding to the active site, the competitive inhibitor prevents the substrate from binding to the enzyme and, consequently, inhibits the catalytic activity of the enzyme.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
