Paracrine signalling Flashcards
1
Q
What is paracrine signalling?
A
Molecules released by one cell act on neighbouring target cells (local diffusion)
2
Q
What are the cell surface receptor subdivision?
A
Ion-channel coupled receptors
G-protein coupled receptors
Enzyme coupled receptors
3
Q
When do ligand gated ion channels open and what happens when they do?
A
Ligands bind to the receptor, causing it to open
Ions flow into the cell
4
Q
What is ACh and what does it do?
A
Acetylcholine - neurotransmitter
Binds to receptors at the neuromuscular junction
