Marcus works in the laboratory of Dr.Flores,an expert in the electrophysiology of squid axons.After taking a reading from a recording electrode placed within a squid axon,Marcus comments to Dr.Flores that the squid axon is at its resting potential.What measurement did Marcus take with the recording electrode?
A)−70 mV
B)−40 mV
C)0 mV
D)+40 mV

Question

Quizplus · Accepted Answer

The resting potential of a squid axon is typically around -70 mV. Therefore, Marcus must have recorded a voltage of -70 mV with the recording electrode.
