Passive Transport Requires no metabolic energy provided by the cell
Diffusion reduces or eliminates a concentration gradient Collisions of particles spread the particles out Solute Solution Solvent NET movement Concentration gradient HIGH concentration LOW concentration Equilibrium SAME concentration SAME concentration
Simple diffusion is passive movement of solutes through a membrane Concentration gradient HIGH concentration LOW concentration
Simple diffusion is passive movement of solutes through a membrane Net diffusion down the concentration gradient may result in equilibrium(a dynamic balance of concentration) NET movement Equilibrium SAME concentration SAME concentration
Channel Concentration gradient HIGH concentration LOW concentration
NET movement Equilibrium SAME concentration SAME concentration
GATED channels Channels are SPECIFIC Channels FACILITATE diffusion LOW concentration GATED channel Channel Concentration gradient HIGH concentration
Impermeant Solute Impermeant solutes cannot cross the membrane NO net movement Concentration gradient HIGH concentration LOW concentration
Osmotic pressure builds up as water moves into cell Impermeant Solute Osmosis is passive movement of water when solutes are impermeant Water molecule WATER gradient LOW concentration SAME concentration HIGH concentration SAME concentration
Carrier NET movement Concentration gradient HIGH concentration LOW concentration Equilibrium SAME concentration SAME concentration
Carriers FACILITATE diffusion LOW concentration Carrier Concentration gradient HIGH concentration
Carriers FACILITATE diffusion LOW concentration Carrier Concentration gradient HIGH concentration
Channels & carriers FACILITATE diffusion LOW concentration Channel Carrier Concentration gradient HIGH concentration
Active Transport Requires metabolic energy (in the form of ATP) provided by the cell
Pumps are ACTIVE carriers HIGH concentration Pump Concentration gradient ADP Pi ATP LOW concentration
Pumps create & maintain a concentration gradient Pumps are ACTIVE carriers HIGH concentration Pump Concentration gradient ADP Pi ATP LOW concentration
