In an experiment, the enzyme lactase is added to milk in a test tube. The products obtained are glucose and galactose. Which of these CORRECTLY explains the function of the enzyme in this reaction? A) The enzyme molecules collide with the substrate and break it into simpler products. B) The enzyme has active sites where the substrate binds with the enzyme to break down the sugar. C) The substrate binds at the non-active sites of the enzyme, where it is broken down into simpler compounds. D) The substrate breaks the bonds of the enzyme, resulting in the formation of simpler products.

b) The enzyme has active sites where the substrate binds with the enzyme to form a complex. When the substrate binds to the active site, an induced fit is formed where the enzyme changes its shape in order to better serve the substrate and lower the activation energy of the reaction
