Cell Membrane: Function – to filter what enters and leaves the cell There are 3 things that can freely get through the cell membrane without energy – Gas, water, and lipids/small molecules Phosphate: “Hydrophyllic” – water loving Lipid Tails: “Hydrophobic” – water fearing Transport Protein There are 2 divisions of how things get through the cell membrane Passive processes – require NO energy (ATP) Active processes – require energy (ATP) NO ATP required Diffusion – movement of molecules from an area of high concentration to an area of low concentration Osmosis – movement of water from an area of high concentration to an area of

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
