CELL MEMBRANE

31
Q
  • Difference in the concentration of a chemical from one place to another (inside to outside)
A

CONCENTRATION GRADIENT

32
Q
  • Difference in the electrical charges between two regions
A

ELECTRICAL GRADIENT

33
Q

term for the charge difference

A

MEMBRANE POTENTIAL

34
Q

Combined influence of the concentration gradient and electrical gradient on the movement of an ion

A

ELECTROCHEMICAL GRADIENT

35
Q

Substances move down or with their concentration or electrical gradient without the use of ATP

A

PASSIVE TRANSPORT

36
Q

random mixing of particles in a solution due to their kinetic energy
- Higher to lower solute concentration

A

DIFFUSION

37
Q
  • substances move freely without
    the help of transport proteins
A

SIMPLE DIFFUSION

38
Q
  • an integral membrane protein (channel or carrier) assists a specific substance
A

FACILITATED DIFFUSION

39
Q

through membrane channels (mostly ion channels) that allow passage of small, inorganic ions

A

CHANNEL-MEDIATED FACILITATED DIFFUSION

40
Q

continuously allow the passage of ions

A

LEAK CHANNELS

41
Q
  • limits the movement of ions by opening/closing the pore by changing shape
A

GATED CHANNELS

42
Q

● A carrier/transporter that changes shape
● Similarities with the Active Transport: transport maximum and saturation

A

CARRIER-MEDIATED FACILITATED DIFFUSION

43
Q

Diffusion of water from an area of higher to lower water concentration; or from an area of lower to higher solute concentration
- Only takes place when a membrane is permeable
to water but impermeable to specific solutes

A

OSMOSIS

44
Q

integral membrane proteins act as
water channels

A

AQUAPORINS

45
Q

A solution that can change the volume by changing its water content

A

TONICITY

46
Q
  • Solution with higher solute concentration and water moves out from the cells
  • Causes cell shrinking or crenation
A

HYPERTONIC

47
Q
  • Solution with lower solute concentration and water moves into the cell

A

HYPOTONIC

48
Q
  • Same concentration on both sides of the membrane
A

ISOTONIC

49
Q
  • Requires cellular energy in the form of ATP
  • ATP is used to move substances against its gradient
A

ACTIVE PROCESS

50
Q
  • Hydrolysis of ATP changes the shape of a carrier protein which pumps a substance across the membrane against its concentration gradient
  • Uses ATP ase
A

PRIMARY ACTIVE TRANSPORT

51
Q
  • The energy stored in an ionic concentration gradient is used (e.g. Sodium)
  • Indirectly uses energy obtained from the hydrolysis of ATP
