Digestive System.
Lactose metabolism primarily occurs in the small intestine. Enzymes called lactase are responsible for breaking down lactose into its simpler forms, glucose and galactose, which can then be absorbed by the body for energy. If lactase is deficient, individuals may experience lactose intolerance.
its an operon required for the transport and metabolism of lactose.
it allows bacteria to regulate the expression of genes involved in lactose metabolism in response to lactose availability. This enables efficient utilization of lactose as an energy source only when needed, conserving cellular resources when lactose is not present in the environment.
Metabolism does not occur in the heart.
If lactose is present, the lac operon in a bacterial cell would be "on." Lactose binds to the repressor protein, causing it to change shape and detach from the operator region of the operon. This allows RNA polymerase to access the promoter and initiate transcription of the genes needed for lactose metabolism. Therefore, the presence of lactose activates the operon.

its an operon required for the transport and metabolism of lactose.
It is an artificial enzyme which takes the place of lactase. It acts as a catalyst by lowering the activation energy of the reaction in which lactose is broken down. This speeds up the metabolism of lactose.
The induction of the lac operon occurs when lactose is present in the environment and glucose is limited. The presence of lactose leads to the activation of the lac repressor protein, allowing RNA polymerase to bind to the promoter region and transcribe the genes involved in lactose metabolism.
Lactose Intolerance occurs in the digestive system.
it allows bacteria to regulate the expression of genes involved in lactose metabolism in response to lactose availability. This enables efficient utilization of lactose as an energy source only when needed, conserving cellular resources when lactose is not present in the environment.
When lactose is absent, the lac operon is typically turned off or repressed. This means that the genes involved in lactose metabolism are not actively transcribed and the production of the necessary enzymes is halted.
Metabolism does not occur in the heart.
Only when lactose is present; if glucose is present the cell will metabolize glucose over lactose due to glucose being easier for the cell to metabolize.
Lactose is present, otherwise the lac operon is not needed and is shut off.
