Which Is/are a Function(s) of the Cytoplasmic Membrane in Prokaryotes

Question

Which is/are a function(s) of the cytoplasmic membrane in prokaryotes?
A) It functions as a permeability barrier.
B) It is an anchor for many proteins involved in bioenergetic reactions and transport.
C) It is a major site of energy conservation.
D) It serves as a permeability barrier, a docking station for proteins involved in bioenergetics reactions and transport, and a site for energy conservation.

Accepted Answer

The cytoplasmic membrane in prokaryotes serves as a permeability barrier to regulate the entrance and exit of molecules, it functions as a docking station for many proteins involved in bioenergetic reactions and transport, and it is a site for energy conservation through the generation of a proton gradient. Choice D includes all of these functions.
