The "Cell-Attached" Patch Clamp Technique

question 22

Multiple Choice

The "cell-attached" patch clamp technique

• A) allows the experimenter to easily change the solution bathing the inside surface of the membrane patch during the recording and study the activity of single voltage-gated channel currents.
• B) allows the experimenter to easily change the solution bathing the outside surface of the membrane patch during the recording and study the activity of single voltage-gated channel currents.
• C) does not allow the experimenter to change the solution on either side of the membrane patch, but you can study the activity of single voltage-gated currents.
• D) allows the experimenter to easily change the solution bathing the inside surface of the membrane patch during the recording and study the summed activity of all voltage-gated channels in the cell (macroscopic current).
• E) allows the experimenter to easily change the solution bathing the outside surface of the membrane patch during the recording and study the summed activity of all voltage-gated channels in the cell (macroscopic current).
