Discussion of all aspects of cellular structure, physiology and
communication. 1 post • Page 1 of 1 Hi. I need help on the
following questions. Please help. Thank you. 1. In a voltage
clamp experiment, Hodgkin and Huxley first clamped an axon at 0
mv and then at +60 mV. Assuming ENa+ is +60 mV and EK+ is -80
mV, when compared with the recording obtained when clamped at 0
mV, the recording at +60 mV showed ________ inward current
followed by ________ in outward current. A. increased; a
decrease B. increased; an increase C. decreased; an increase D.
increased; no change E. decreased; a decrease 2. If EK is -80
mV, what is the net driving force on K+ when an axon is voltage-
clamped at -100 mV? A. 20 mV inward B. 180 mV inward C. 20 mV
outward D. 180 mV outward E. 0 mV because membrane potential is
more negative than the equilibrium potential 3. In the resting,
unstimulated neuron, activation gates of most sodium channel
are____ inactivation gates of most sodium channels are_____ and
activation gates of most volt
