What happens when maltose is hydrolyzed? 

Two molecules of glucose are formed. 

The correct answer is option 1. Two molecules of glucose are formed.

When maltose is hydrolyzed, the correct option is two molecules of glucose are formed.

Maltose is a disaccharide composed of two glucose molecules linked together. Hydrolysis of maltose involves breaking this bond through the addition of water, resulting in the formation of two separate glucose molecules. The chemical equation for the hydrolysis of maltose is:

\[ \text{Maltose} + \text{Water} \rightarrow 2 \text{Glucose} \]

Therefore, the end products of maltose hydrolysis are two molecules of glucose.
