Which of the following statement is true?
a. The active site is only a small part of the total enzyme volume.
b. The active site of an enzyme is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
c. According to Kosland's induced fit theory, the active site is inflexible and cannot change shape during the catalytic process.
d. An active site can catalyze a reaction repeatedly as the amino acid residues involved in the catalytic process are not altered at the end of the enzymatic reaction.
e. When an enzyme's substrate binds the active site, water usually exists the site for catalysis to occur.


Sagot :

Answer:

The active site of an enzyme is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Explanation:

This is because enzymes catalyses reaction by first lowering it activation energy and then bind to the reactants and convert the substrate to products. This take place in the active site. This active site is that area or region where the activation energy is lowered and the substrate molecules is bind to produce products.
