Since you know what Glucose Oxidase is I'm assuming you know what enzymes are. If not, an enzyme is a protein that catalyzes chemical reactions.

Glucose oxidase is the enzyme built specifically for Glucose. Glucose Oxidase binds to the six-carbon sugar Glucose and aids the organism in breaking it down into metabolites.

Catalase degrades easily at room temperature b. Glucose oxidase is inactivated at low pH c. Glucose oxidase is only active at low pH d. Glucose oxidase has a higher molecular weight than catalase .

The sticks contain enzymes (glucose oxidase and peroxidase) which react in the presense of glucose. The glucose oxidase changes glucose into gluconic acid and hydrogen peroxide and the peroxidase reacts with that hydrogen peroxide to change a pigment in the stick from neutral color to positive color.

Glucose oxidase that converts the carbonyl (aldehyde) carbon of glucose to a carboxylic acid.
