Membrane Transport system - Coggle Diagram
Membrane Transport system
Osmosis
Definition
:
2 Requirements
1.
There must be a difference in solute concentration, and not at equilibrium or else there would be no movement
Has to be at different solute concentratiosn
2.
Membrane is impermeable to solute. Water can go through, but solute should NOT be able to go through.
Types of Solution
Hyposmotic is when obne solution has lower concentration
Hyperosmotic is when one solution has a higher concentration
Isosmotic is 2 solutions with the same concentration
movement of water from high concentration to lower concentration.
Tonicity
Definition
:
Hypotonic:
More particles inside of cell
*Isotonic:
Cell is at equilibrium
Hypertonic:
Hypertonic is when more solute/particles are outside the cell, so the solute/particles suck them up = shrivels
describes the change of the cell depending on water movement.
Active Transport
Endocytosis (going into the cell) & Exocytosis (going out of the cell) & Phagocytosis (eating them whole)
Channel proteins, Carrier proteins, gates
Carrier Protein
Uniport
Symport
Antiport
Active: Does require ATP (from low to high concentrations)
Primary & secondary active transport, Na/K pump
Passive Transport
Diffusion: From high to low concentration
Facilitated Diffusion: High to low concentration (needs help to diffuse) - proteins needed
Passive: Does not require ATP
