CELL TRANSPORT MOVING MATERIAL ACROSS THE CELL MEMBRANE

PASSIVE TRANSPORT Movement of materials across the cell membrane must be regulated to maintain homeostasis inside the cell.

CELL MEMBRANE- IDENTIFY THE COMPONENTS

BACKGROUND INFO Solute- what is dissolved in solution Solvent- what does the dissolving- often water Solution- solute + solvent

PASSIVE TRANSPORT #1 Diffusion - Solute particles move from an area of high concentration to low concentration Example – food coloring and water No use of cellular energy

EXAMPLES ON BOARD Use your whiteboards to predict movement of solute.

FACILITATED DIFFUSION- PASSIVE TRANSPORT 2 Solute molecules pass through protein channels and diffuse faster than expected Kind of like a short cut Still passive transport- not cellular energy required

PASSIVE TRANSPORT #3 Osmosis - water moves from low solute concentration to high solute concentration, or the water moves from area of high water concentration to low- still a type of diffusion The big idea is that the solvent moves not the solute These processes happen to achieve equilibrium or balance Aquaporins- channel proteins that allow water to pass Osmotic pressure- water pressure due to osmosis

EXAMPLES OF OSMOSIS ON BOARD Use your white boards.
