Q

bulk transport

A

large particles (macromolecules) exit or enter using endocytosis or exocytosis

21
Q

diffusion

A

High to low (no energy)

22
Q

solution

A

solvent (water) and solute (solid/ usually the thing that spreads)

23
Q

osmosis

A

diffusion of water

24
Q

osmotic pressure

A

pressure in system due to osmosis

25
Q

isotonic

A

equilibrium equal in and out

26
Q

hypotonic

A

water in more than out

27
Q

hypertonic

A

water out more than in

28
Q

turgor pressure

A

pressure in a plant cell

29
Q

lysis

A

bursting of cell

30
Q

crenation

A

creating a raisin shriveling of cell

31
Q

plasmolysis

A

shrinking of cell

32
Q

facilitated transport

A

rapid transport with carrier proteins- passive and active

33
Q

active transport

A

requires energy

34
Q

sodium potassium pump

A

3 sodium exit the cell requiring energy ( a phospate attatches to protein) 2 potassium then enter Phosphate is released from the protein. this is used by same carrier protein and causes the inside of the cell to be less positively charged than the out side

35
Q

receptor mediated endocytosis

A

pinocytosis that cells to realize specific molecules tho bring them in as a vesicle

36
Q

Extracellular Matrix

A

EMC- collage and elastin fibers have a support function while fibronectins bind to intergin and in this way, it assist communication between ECM and the cytoskeleton

37
Q

fibronectin

A

adhesive property

38
Q

intergins

A

integral proteins connected to fibronectin and cytoskeleton- plays role in cell signalling

39
Q

proteoglycans

A

aminoicids connected to polysaccharides (bottle brush) signaling

40
Q

adhesion junctions

A

mechanically attach adjacent cells *most common

41
Q

desmosomes

A

type of adhesion junction

42
Q

tight junction

A

impenetrable barriers adjacent cells joined together

43
Q

gap junction

A

all for communication - 6 membrane proteins that allow molecules through

44
Q

cell wall

A

in plants

45
Q

plasmodesmata

A

numerous narrow membranes lined channels that pass through cell walls

46
Q

endocutosis

A

take in forming a vesicle engulfs

47
Q

exocytosis

A

spits out opp of endocytosis

48
Q

phagocytosis

A

solids in

49
Q

pinocytosis

A

fluids in
