The enzyme-substrate complex is formed in which part of the enzyme molecule?
Correct answer: A. Binding site
- A. Binding site
- B. Allosteric site
- C. Catalytic site
- D. None of the above
Explanation
The enzyme-substrate complex is formed in the binding site of the enzyme molecule. This is the specific region of the enzyme that recognizes and binds to the substrate, leading to the formation of the complex. The binding site is a highly specific region that allows only certain substrates to bind to the enzyme, based on their size, shape, and chemical properties. Once the complex is formed, the catalytic site of the enzyme can then carry out the chemical reaction to convert the substrate into the product.

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.
