Use the lac operon to explain how genes can be turned on or off to control the expression of a protein (enzyme)? I need serious help! I don't understand. Just a few sentences that get to the point will do fine! Please help!

The lac operon is an inducible operon that utilizes lactose as an energy source and is activated when glucose is low and lactose is present. The lac operon contains an operator, promoter, and structural genes that are transcribed together and are under the control of the catabolite activator protein (CAP) or repressor. The lac operon is not activated and transcription remains off when the level of glucose is low or non-existent, but lactose is absent. The lac operon encodes for the genes needed to utilize lactose as an energy source. https://www.boundless.com/biology/textbooks/boundless-biology-textbook/gene-expression-16/prokaryotic-gene-regulation-112/the-lac-operon-an-inducer-operon-456-11681/
