Due to the similarity of structure, competitive inhibitors may be selected by the _ site.
Correct answer: B. Active
- A. Catalytic
- B. Active
- C. Binding
- D. Allosteric
Explanation
Competitive inhibitors are structurally similar to the substrate and therefore can bind to the same region of the enzyme where the substrate normally attaches. This region is broadly referred to as the binding site.While in most enzymes the binding site and the active site are the same, the term "binding site" is more accurate in a general biochemical context. It encompasses any part of the enzyme where a molecule - whether it's a substrate, inhibitor, or cofactor - can bind.

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.
