1.

A researcher is studying two enzymes, Amylase and Glycoside Hydrolases, which both catalyze the breakdown of different carbohydrates. Amylase works best on starch, while Glycoside Hydrolases works best on cellulose.

When cellulose is added to a solution containing only Amylase, no reaction occurs. Which of the following best explains this observation?
