Membrane Transport Lion Den Slide Collection By Kevin Patton User Manual Click each slide to advance it
2
Passive Transport Requires no metabolic energy provided by the cell
3
Solute Solvent HIGH concentration LOW concentration Concentration gradient SAME concentration SAME concentration Equilibrium Solution NET movement Diffusion reduces or eliminates a concentration gradient Diffusion reduces or eliminates a concentration gradient Collisions of particles spread the particles out Collisions of particles spread the particles out
4
HIGH concentration LOW concentration Concentration gradient Simple diffusion is passive movement of solutes through a membrane Simple diffusion is passive movement of solutes through a membrane
5
SAME concentration SAME concentration Equilibrium NET movement Net diffusion down the concentration gradient may result in equilibrium (a dynamic balance of concentration) Simple diffusion is passive movement of solutes through a membrane Simple diffusion is passive movement of solutes through a membrane
6
HIGH concentration LOW concentration Concentration gradient Channel
7
SAME concentration SAME concentration Equilibrium NET movement
8
Channel HIGH concentration LOW concentration Concentration gradient GATED channel GATED channel Channels are SPECIFIC Channels are SPECIFIC GATED channels GATED channels Channels FACILITATE diffusion
9
HIGH concentration LOW concentration Concentration gradient NO net movement Impermeant Solute Impermeant Solute Impermeant solutes cannot cross the membrane
10
Aquaporins are tiny channels that facilitate water movement
11
Impermeant Solute Impermeant Solute Water molecule LOW concentration HIGH concentration WATER gradient SAME concentration Osmosis is passive movement of water when solutes are impermeant Osmotic pressure builds up as water moves into cell
12
SAME concentration SAME concentration Equilibrium NET movement HIGH concentration LOW concentration Concentration gradient Carrier
13
Carriers FACILITATE diffusion HIGH concentration LOW concentration Concentration gradient
14
Carrier Carriers FACILITATE diffusion HIGH concentration LOW concentration Concentration gradient
15
HIGH concentration LOW concentration Concentration gradient Carrier Channel Channels & carriers FACILITATE diffusion
16
Active Transport Requires metabolic energy (in the form of ATP) provided by the cell
17
ATP ADP PiPi PiPi Pump Pumps are ACTIVE carriers Pumps are ACTIVE carriers LOW concentration HIGH concentration Concentration gradient
18
ATP ADP PiPi PiPi Pump Pumps are ACTIVE carriers Pumps are ACTIVE carriers LOW concentration HIGH concentration Concentration gradient Pumps create & maintain a concentration gradient Pumps create & maintain a concentration gradient
19
