Lactase is a protein enzyme that digests (breaks down) lactose (milk sugar) into glucose and. galactose (smaller sugars). The chemical equation below illustrates what happens when the. enzyme lactase digests lactose (milk sugar).
Bottom: The gene is turned on. Lactose is inhibiting the repressor, allowing the RNA polymerase to bind with the promoter, and express the genes, which synthesize lactase. Eventually, the lactase will digest all of the lactose, until there is none to bind to the repressor.ottom: The gene is turned on.
