The enzyme-substrate complex is formed in which part of the enzyme molecule?
Correct answer: A. Active site
- A. Active site
- B. Allosteric site
- C. Catalytic site
- D. None of the above
Explanation
The correct answer is the active site, which is the specific region of the enzyme where the substrate binds, forming the enzyme-substrate complex. This interaction is crucial for catalysis as it aligns the substrate for the chemical reaction. The allosteric site affects enzyme activity through regulation but does not participate in the initial substrate binding. The catalytic site is often considered part of the active site, focusing on the chemical transformation aspect rather than the initial binding.

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.
