True or false. Look at the figure above to answer the questions below. _______ Resting potential is generated only by the movement ions. _______ The voltage differences shown above are measured across the plasma membrane (not deep within the cell). ______
The changes in voltage seen at #2 and #4 in the figure caused by movement of the same types
of ions across the membranes.
_______
_______
_______
The trace above is following the voltage change as down the axon.
The voltage change above is an all-or-nothing response.
Different membrane proteins are responsible for generating
the voltage change seen at #2 and #4
in the figure.
_______
_______
All voltage changes in a neuron's plasma membrane characteristic shape shown above.
The changes in voltage shown above are due to the of ions right through the plasma
membrane phospholipids bilayer (without the presence accessory protein).
What will be an ideal response?
f Resting potential is generated only by the movement of K+ ions.
f The voltage differences shown above are measured just across the plasma membrane (not
deep
within the cell).
f The changes in voltage seen at #2 and #4 in the figure are caused by movement of the
same types
of ions across the membranes.
f The trace above is following the voltage change as it moves down the axon.
t The voltage change above is an all-or-nothing response.
t Different membrane proteins are responsible for generating the voltage change seen at #2
and #4
in the figure.
f All voltage changes in a neuron's plasma membrane have the characteristic shape shown
above.
f The changes in voltage shown above are due to the diffusion of ions right through the
plasma
membrane phospholipids bilayer (without the presence of an accessory protein).
