Synaptic communication Flashcards
1
Q
What are the limitation of electrical signaling?
A
Binary, difficult to modify, energy intensive, and microenvironment dependent
2
Q
What do ATPases do?
A
Create ion concentrations gradients using ATP
3
Q
What ion is always leaking in and out of a cell?
A
Potassium
4
Q
When calculating the charge…
A
It’s the movement of ions
5
Q
What are some ion channels?
A
Leakage, voltage-gated, ligand-gated, physically gated
6
Q
What some ion transporters?
A
ATPase, ion exchangers, co-transporter, multiple transporter systems
7
Q
Where are action potentials initiated?
A
The axon hillock
8
Q
What are the two ways to increase an action potential?
A
1) Increase the Axon caliber
2) Insulate axons
