name some functions of membrane proteins
ion channels, carriers, receptors, enzymes, linkers, identity makers
difference between integral and peripheral proteins
integral proteins go through the membrane and peripheral proteins sit on the surface
what is passive transport
movement of substances across the membrane without using ATP
what is diffusion
movement of particles from high to low concentration
what is facilitated diffusion?
diffusion with help from proteins for molecules too large to pass alone
what is osmosis
Diffusion of water across a selectively permeable membrane.
what are real life examples of diffusion
perfume spreading in a room
what is a real life example of osmosis
water moving in/out of cells in contact lens solution
what is a concentration gradient
difference in concentration between two areas
