Opposite of Simple Diffussion, material moves up the concentration gradient, uses ATP and a carrier protein.
Carrier Protein [Transport Protein]
Just like an enzyme, found in facilitated diffusion, and active transport.
When cell shrinks by losing H20
A difference in concentration of a substance over a distance.
entire contents of the cell, except the nucleus, bounded by the plasma membrane.
the movement of a substance down its concentration gradient from a more concentrated area to a less concentrated area.
the cellular uptake of materials in which the plasma membrane surrounds and engulfs extracellular materials
Cells REMOVE waste material
the spontaneous passage of molecules and ions, bound to specific carrier proteins, across a biological membrane down their concentration gradients.
for material to move, RIGHT chemical must be present
lipid covalently linked to a sugar or polysaccharide, an important part of animal cell membranes
protein linked to a sugar or polysaccharide, component of receptor molecules on the outer surface of cells
Over, above, in excess, 70% H20, 30% Stuff
Lower, less in environment
equal amount of stuff and stuff, H20 and H20
Simple diffusion of water H20
Animal version of hypotonic diffusion
the diffusion of a substance through a biological membrane
type of endocytosis, cell EATING
type of endocytosis, cell DRINKING
always open for material pending on size and charge
false feet, cell engulfs
Selectively Permeable Memberane
allowing some substances to cross while preventing others from crossing
Movement of material from high to low concentration
plant version of hypotonic diffusion
Area where materials are moved in cytosis
