types of cell junctions/transport

these allows communication between cells/ send ions to the adjacent cells

gap junctions

this are known as anchoring junctions they can connect two cells but still give some flexibly

desmosomes

facilitated diffusion

uses channel proteins to move molecules from a high concertation to low concertation.

phosphorylation of a protein to push something against its concentration gradient is called

primary active transport

the gradient formed from the sodium potassium pump a primary form of active transport is an example of what

secondary active transport.
