Operon: Lac trp Is the metabolic pathway anabolic or catabolic
... 1. Under what circumstances would the lac operon be “on” versus “off”? The trp operon? The lac operon would be off when there is no lactose in the cell. The lac operon would be on when lactose is present and there is little or no glucose in the cell. However, the lac operon would be off (or operatin ...
