Basic anatomy and kinsiolgy cells (part 2

no energy required; move down a concetration gradient (high concentration a lower concentration)

diffusion, osmosis, dialysis, and filtration. What transport processes ?

substances move from one area of concentration to an area of lower concentration; move down a concetration

diffusion of water through a selectively permeable membrane

difussion of small solute particles across a selectively permeable membrane. some solutes pass and others fo not

movement of water and solutes through a filtration membrane; movement from high pressure areas to low pressures. Ex. This is partially responsible for moving water and small solutes from blood into fluid spaces of body tissues; also wastes are filtered from blood to kidney tubules.

substances move up the concentration gradient; requires energy for ATP. (lower concentration to higher concentration)

What are the three types of active transport

____ is a protein complex in the cell membrane and use energy from ATP to move substances across cell membranes against their concentration gradients.

Term mean cell eating. Engulfs large particles in a vesicle as a protective mechanism (ex. bacteria)
