Question

Which of the following is a primary function of the active site of an enzyme?

1) Binding the substrate
2) Catalyzing the reaction
3) Regulating enzyme activity
4) Transporting molecules

Answer 1

The primary function of the active site of an enzyme is binding the substrate, which allows the enzyme to catalyze the reaction. The active site also helps in positioning the substrate and releasing the product.

Step-by-step explanation:

The active site of an enzyme has several important functions, but a primary function is binding the substrate. The active site is where the substrate molecule binds to the enzyme, forming an enzyme-substrate complex. This binding interaction allows the enzyme to catalyze the reaction by facilitating the making and breaking of bonds in the substrate molecule. Other functions of the active site include positioning the substrate molecules correctly for the reaction and releasing the product molecules after the reaction.
