Your cars gas tank is full and you take a trip. You travel 212 miles, then you fill your gas tank up again and it takes 10.8 gallons. If your change in distance is 212 miles and your change in gallons is 10.8, what is the average rate of change of gasoline used, measured in miles per gallon?
Action Potential Propagation 09/21/2015 conduction of AP: action potential = CHANGE IN PERMEABILITY of membrane generated at axon hillock passive spread of cations through axon depolarization of membrane: o opening of channels create more permeability crosses threshold – voltage gated sodium channels open in initial segment: influx of Na+ - positive charge spreads passively BOTH downstream and upstream (passive depolarization on both sides of initiation side) downstream flow charges next segment of axon: + charge depolarizes this segment to threshold voltage-gated Na+ chan
