Acetal formation (glycosidic linkage) between glucose and galactose by condensation reaction.
It can also be seen as dimerisation of two monosaccharides (Glu + Gal) to one disaccharide
(Lactose is: β-D-galactopyranosyl-(1→4)-D-glucose)
The chemical equation for the breakdown of lactose by lactase is: C12H22O11 (lactose) + H2O → C6H12O6 (glucose) + C6H12O6 (galactose). Lactase is the enzyme that catalyzes this reaction, breaking down lactose into its constituent monosaccharides, glucose, and galactose. This process is essential for the digestion of lactose in individuals who are lactose intolerant.
Enzymes catalyze reactions by lowering the activation energy required for a chemical reaction to occur. They do this by binding to specific substrates and bringing them together in the correct orientation to facilitate the reaction. This process, known as catalysis, speeds up the reaction without being consumed in the process.
The product of the chemical reaction is released from the active site of an enzyme. The substrate is converted into product during the enzymatic reaction, and once the reaction is complete, the product is released to allow the enzyme to catalyze another reaction.
An enzyme-substrate complex is formed when an enzyme binds to its substrate molecules. This temporary complex allows the enzyme to catalyze a specific chemical reaction by lowering the activation energy required for the reaction to occur. Once the reaction is complete, the products are released and the enzyme is free to catalyze another reaction.
No, enzymes are specific in their function and can only catalyze specific reactions.
If a lactase molecule is used up in a reaction, you would observe a decrease in the rate of lactose breakdown. This decrease occurs because there are no more lactase molecules available to catalyze the reaction. Additionally, if all lactase molecules have been used up, there will be a point where no further lactose can be broken down in the reaction.

Lactase breaks down lactose through hydrolysis, which is a chemical reaction that involves the breaking of a bond by water. In this process, lactase enzyme catalyzes the reaction that breaks lactose into its two components, glucose and galactose.
The reaction would be termed a chemical reaction.

They are used to, with an unexpected degree of efficiency, catalyze a specific chemical reaction. This means maximizing harmless and useful chemical-reaction products while minimizing the [inevitable] wasteful and useless byproducts of the chemical reaction.
Enzymes catalyze certain reactions.
The main thing that an enzyme does to catalyze a reaction, is to lower the energy of reaction.
