When E. cоli bаcteriа encоunter а lоw-glucose environment but lactose is present, the lac operon becomes active. Which of the following describe what happens as glucose disappears while lactose is present? Select true or false for each scenario. The cAMP-CAP complex binds to the lac operator and directly inhibits transcription of the lac genes. [blank1] LacI releases from the operator when bound by allolactose, allowing RNA polymerase to transcribe the genes needed for increased lactose metabolism. [blank2] Lactose directly binds RNA polymerase, increasing its activity on the lac operon. [blank3] Functional lacY products promote lactose import. [blank4] Functional lacZ products cause an increase in allolactose in the cell. [blank5]
