cholesterol

A

stabilize and maintain membranes

24
Q

are able to move around and within the membrane

A

proteins

25
Q

different types of proteins

A

rotational lateral and transverse diffusion of the proteins
the list common is transverse

26
Q

outer membrane to inner membrane. usually get rotational and lateral movement within the membrane but will not see flip-flop, very often.

A

flip-flop (only time to see transverse diffusion)

27
Q

phospholipids above their axes can occur

A

rotation

28
Q

can also move within the monolayer, via lateral diffusion

A

phospholipids

29
Q

found in the outer or inner layer. they are dynamic and act as a point of binding for cytoplasm. Help information organization formation in cytoplasm and help in cell signaling and transportation.

A

lipid raft

30
Q

act as detect and respond to extracellular signal

A

cytoskeleton

31
Q

transport nutrients and ions across the membrane
binding activated immune system cells to their microbial target
transporting toxin into intestinal fluid

enzymes are characterized by the

A

sensitivity to temperature

39
Q

are usually metals ions or small organic molecules called coenzymes ( a lot of them require cofactors)

A

prosthetic group

40
Q

they increase reaction rates by lowering the activation energy needed.
They formed transient, reversible complexes with substrate molecules.
they change the rate at which equilibrium is achieved, not the position on the equilibrium.

what overomme activation barrier

A

catalysts

42

46
Q

what bind to active side of an enzyme

A

competitive inhibitors

47

A

non competitive

47
Q

what binds to inhibitor side and alters the active side, causing conformation changes?

A

non competitive

48
Q

term to be like poison, binds to the enzyme covalently, causing permanent loss of catalytic activity, and are generally toxic to cells

A

irreversible inhibitors

49
Q

bind to enzymes noncovalently and can dissociate from the enzyme.

A

reversible inhibitors

heavy metal ion, nerve gas poisons, some insecticieds

51
Q

means permanent loss of cartilage activating in the enzyme

A

covalent binding.
