In competitive inhibition, the inhibitor has similar _ to the substrate.
Correct answer: D. Structure
- A. Chemical properties
- B. Chemical formula
- C. Physical properties
- D. Structure
Explanation
In competitive inhibition, the inhibitor has a similar structure or shape to the substrate. The competitive inhibitor competes with the substrate for binding to the active site of the enzyme. Because the inhibitor closely resembles the substrate, it can bind to the active site and block the substrate from accessing the same binding site. This competition between the substrate and the inhibitor for the active site is a key characteristic of competitive inhibition.

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.
