Cell Transport, ALINE GUADALUPE ARELLANO SANCHEZ - Coggle Diagram
Cell Transport
with a concentration gradient
Passive Transport
Doesn't use energy
classifies in
Facilitated diffusion
Movement of molecules that are not fat-soluble with the help of a protein (channel or carrier),
with the concentration gradient
hydrophilic molecules
ionic channel proteins
transports

Ligand-gated ion channels
Voltage-gated ion channels
hydrophobic molecules
carrier protein
transports
1 more item...
Simple diffusion
Movement of small molecules that are fat-soluble,
with the concentration gradient.
Osmosis
Water movement through a semipermeable membrane, from the end with the lower concentration of solute towards the end with the higher concentration.
forms of transport
uniport
only one molecule is being transported
against the concentration gradient
Active Transport
Always uses energy
classifies in
uses entropy as an energy source
Secondary
When one molecule moves down with its concentration gradient a tiny bit of energy is lost (entropy). This bit of energy can be used to cotransport a second molecule up its gradient.
forms of transport
symport
2 more items...
Vesicular
when a little capsule surrounded by a cell membrane transports large molecules or multiple at once
types
molecules go
out of the cell
Exocytosis
molecules enter
into the cell
Endocytosis
2 more items...
proteins
involved include
clathrin
surrounds the vesicle, folding it and giving it a round shape
dynamin
pinches the membrane, releasing the vesicle
v-SNARE
1 more item...
uses ATP as an energy source
Primary
Movement of substances against the concentration gradient.
