- The voltage produced by a single nerve or muscle cell is quite small, but there are many species of fish that use multiple action potentials in series to produce significant voltages. The electric organs in these fish are composed of specialized disk-shaped cells called electrocytes. The cell at rest has the usual potential difference between the inside and the outside, but the net potential difference across the cell is zero. An electrocyte is connected to nerve fibers that initially trigger a depolarization in one side of the cell but not the other. For the very short time of this depolarization, there is a net potential difference across the cell, as shown. Stacks of these cells connected in series can produce a large total voltage. Each stack can produce a small current; for more total current, more stacks are needed, connected in parallel. In an electric eel, each electrocyte can develop a voltage of 150 mV for a short time. For a total voltage of 450 V, how many electrocytes must…arrow_forwardPlease answer both 1) What is responsible for returning the cell to its normal resting membrane potential following the absolute refractory period? a) K+ leak channels b) the Na+/K+ pump c) activation of voltage-gated Na+ channels d) a ligand binding to a ligand-gated Na+ channel 2) What property of an action potential allows it to propagate? a) the rapid period of depolarization b) the rapid period of repolarization c) the brief period of hyperpolarization d) the fact that the peak is 85 mV above thresholdarrow_forwardMork is an alien from planet Ggle674. Mork finds a car and tries to figure out how it works. The alien places a sensor on a wire coming from the alternator when the car is started. Mork's sensor detects an electrical current of 12 volts coming from the alternator. Mork's experiment is most closely related to the method called 1) single cell recording. O 2) EEG O 3) ablation. O 4) functional magnetic resonance imaging. O 5) transcranial magnetic stimulation.arrow_forward
