Cell transport, New terms - Coggle Diagram
Cell transport
passive transport
does not requires energy
simple difussion
non polar
small
molecules
water
CO2
directly pass through the phospholipid bilayer
Facilitated difussion
uses channel proteins
polar
large
molecules
glucose
moves with the concentration gradient
from high to low concentration (with the concentration gradient)
Osmosis
Uses aquaporins (special channel protein that only water can use)
movement of water molecules through a membrane from high to low concentration of water
it can use simple and facilitated diffusion
active transport
requires energy (ATP)
adenosine triphosphate
when the last covalent bond is broken then it releases energy
substances move from low to high concentration (against the concentration gradient)
Using channel proteins
larger
molecules
polar
cytosis
too large proteins
Using the whole membrane
types
The cell membrane controls what goes in and out in order to maintain homeostasis
the cell is partially permeable
New terms
SOLUTION
Solute + solvent
SOLUTE
Hydrophilic
polar
SOLVENT
water
ISOTONIC
same concentration of solute and solvent
HYPERTONIC
more solute and less solvent
HYPOTONIC
less solute and more solvent
