24
Q

________ protein binding occurs fast and directly

25
______- protein binding occurs slowly and indirectly
metabotropic
26
during _________, molecules will move so as to be distribute equally
diffusion
27
the ______________ refers to how much of a molecule in one place
concentration gradient
28
Polarity/charge is determined by _________
electrons
29
Ion Pump requires energy in the form of _____ to move against the electric potential
ATP
30
___________ is when a neuron becomes more | negative
hyperpolarization
31
_________ is when a neuron becomes more | positive
depolarization
32
depolarization happens in the _____________
Excitatory Postsynaptic Potential (EPSP)
33
hyperpolarization happens in the ______________
Inhibitory Postsynaptic Potential (IPSP)
34
what problems occur during depolarization and what is the solution/
Problem: cells that reach “0” are dead cells!! Solution: Rapid change
35
_________ refers to an integration of presynaptic responses
summation
36
_______ Summation is when several neurons fire together
Spatial
37
what are the stages of signalling action potential
1. Resting 2. Threshold: voltage gated Na+ channels (VGC) open (Na+ influx) 3. Depolarization: more Na+ VGC channels open (Na+ influx) 4. Repolarization: K+ VGC open (K+ exit) 4.5 Absolute Refractory Period: NA+ VGC close, K+ VGC still open ➢Note: this is why the Action potential goes in one direction 4.5 Hyperpolarization: K+ VGC closes 5. Relative Refractory Period
