Where is disaccharidase produced and where is it active?

Disaccharidase is produced in the intestinal lining and is active in the small intestine.

What does it mean for an active site to be flexible?

Many enzymes can stretch and enclose around the substrate to form the perfect environment for the reaction about to take place: the induced fit. When the reaction is finished, the enzymes retract back to their initial shape and repeat the process for the next reaction.

Proteins

About how much faster can reactions occur in the presence of an enzyme?

Reactions can occur millions to trillions of times faster with the presence of an enzyme than without one.
