Verified step by step guidance

Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in living organisms. Each enzyme is specific to a particular reaction or type of reaction.

Review the function of each enzyme listed: Glucose Oxidase, Sucrase, Deaminase, and Pepsin. Ensure you know the typical reactions they catalyze.

Glucose Oxidase: This enzyme catalyzes the oxidation of glucose, converting it into gluconic acid and hydrogen peroxide. This match is correct.

Sucrase: This enzyme catalyzes the hydrolysis of sucrose into glucose and fructose. This match is correct.

Deaminase: This enzyme typically catalyzes the removal of an amino group (NH2) from a substrate, not the addition of NH3. This match is incorrect, as the function described does not align with the typical activity of deaminase enzymes.
