Cell Membrane - Coggle Diagram
Cell Membrane
Membrane Structure
Phospholipids
Polar non polar tail
Constantly in motion
Cholesterol
stabilizes cell
Glycoprotien
send and receive signals and used as antenas
send and receive signals
Diffusion
Concentration gradient(difference in concentration between 2 areas)
Passive(with concentration gradient)
Facilliated(with concentration gradient)
Active(without concentration gradient)
Endocytosis(Engulfs and moves molecule into cell for really large molecules)
Requires glycol proteins or lipid to receive a signal
Exocytosis(Engulfs and moves molecule out to the cell for really large molecules)
Requires glycol proteins or lipid to receive a signal
Osmosis
Movement of water across the membrane
moves with concentration gradient
Water is easdier to move in and out of membrane so it is generally used to balance enviroment
Aquaporin makes it easy for water to move
Cell use osmosis to deliver nutrients and remove waste
Tonicity
Hypertonic
net movement is outwards
Idotonic
Equal net movement
Hypotinic
net movement is inwards
Tonicity depends on the concentration of the fluid inside and outside the cell
Functions
Protection
Regulation
Communication
Membrane related Illnesses
Diabetes
Type 1
Body cannot produce Insulin and is genetic
Type 2
Insulin receptors do not work and is developed over time
Virus
Uses cell receptors to enter cell
Takes over cell to produce more viruses
Plants
Vacuole
The central vacuole helps a plant maintain turgor pressure • Turgor pressure is caused by the contents of the cell
Plants need Hypotonic solution
Turgor pressure help plants keep shape
