It's about lacZ E coli's failure to showing galactoside permase activity after adding lactose without glucose's presence. why ?

SUMMARY
The discussion centers on the lacZ gene in E. coli and its galactoside permase activity in the absence of glucose. It is established that the presence of glucose inhibits the expression of the lac operon, leading to a lack of galactoside permase activity even when lactose is present. The referenced resource clarifies that both glucose and lactose must be considered to understand the operon's regulation accurately.
PREREQUISITES- Understanding of the lac operon mechanism in E. coli
