Document Summary
How can a membrane be both: an impermeable barrier between the inside and the outside of the cell, a structure that allows cells to take in energy rich molecules from outside the cell. Lipid rafts: key membrane functions, membrane bilayer, membrane lipids. Mechanisms of protein association to the membrane. Membrane protein modifications: membrane protein diffusion. Key membrane functions: plasma membrane separates and maintains the living properties of the cell/ is a barrier that separates the living world from the non-living world) Has to be an semi- impermeable and semi- impenetrable wall so certain harmful substances cannot get in a(cid:374)d (cid:374)o(cid:374)e of the (cid:272)ell"s (cid:272)o(cid:373)po(cid:374)e(cid:374)ts get out: internal membranes compartmentalize the eukaryotic cell to form organelles. The plasma membrane is similar to the membranes around other organelles (like er and. Ga: maintains ion and chemical gradients, controls material exchange between the cell and its environment.
