Title
Question
'Observe that LacY protein binds to the Cell Membrane.'
The protein doesn't bind to the cell membrane from inside or outside. It is inserted into the membrane and allows the transport of lactose molecules into cells.

Answers:

The term bind was used to describe the LacY associated with the cell membrane as shown on simulation screen.

In real cells it will be located inside the cell membrane.

Lac Y as you call it, or the permease may be inserted from the inside of the cell where it is produced but for it to allow transport of lactose molecules into the cell, it must provide an actual channel through the cell wall. Binding to the cell membrane from inside or outside won't do.
