enzymatic concentration
substrate
Plasma membrane (5 proteins)
Channel protein Carrier protein Cell recognition protein Receptor protein Enzymatic protein
Solvent
The one that is prepared to be mixed by the solute
ex: water
Solute
The one that is going to mix with the solvent
ex: sugar
Concentration Gradient
2 types:
- ATP is required / HIGH to LOW concentration
- ATP is NOT required / LOW to HIGH concentration
Hypotonic solution
Net water gain
Cell swells
Hypertonic solution
Net water loss
Cell Shrinks
Isotonic solution
No let loss or gain
Passive transport difussion
Facilitated
diffusion
Osmosis
▹ Movement of water
▹ High to low
▹Water molecules
▹It does NOT energy
