What influences the movement of ions and molecules across cell membranes?

A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move.
Please see the related link below which includes a diagram of how ions affect membrane potential.

How does facilitated diffusion work?
It is a passive process utilizing a protein carrier or channel.
What is required to transport glucose molecules across the cell membranes of the intestine?
To start the process ATP is required to transport glucose milecules across the cell membranes of the intestine.
What is the function of active transport in moving small molecules and ions across cell membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What does osmosis have to do with cell membranes?
Osmosis is the water molecules diffusion across the cell membranes. More informations can be find at en.wikipedia.org/wiki/Diffusion
