PLEASE HELP WITH Q6

Page 1b of 18 6. Use the illustration below and the provided boxes to answer questions 6 A to D. (4.5 pts) A) Inside each of the ampliers in the illustration below (triangles), place an A (for the voltage clamp amplier), a B (for the amplier that reads the membrane voltage) or a C (for the amplier that measures current). (0.5 pts each, 1.5 pts total) B) Along the dotted horizontal line in the box provided (labeled I), draw the early, late, and capacitative currents that would be recorded by the voltage clamp device upon depolarization of the ' membrane voltage from about -65 mV to 15 mV. (1 pt) C) In the box labeled H, draw the equivalent currents as depicted in box I, but this time in the presence of TTX or after depletion of external Na+ ions. (1 pt) D) In the box labeled III, draw the equivalent currents as depicted in box I, but this time in the presence of TEA. (1 pt) 4 Feedback current Command voltage Squid axon
