An electric eel generates electric currents through its highly specialized Hunter’s organ, in which thousands of disk-shaped cells called electrocytes are lined up in series, very much in the same way batteries are lined up inside a flashlight. When activated, each electrocyte can maintain a potential difference of about 150 mV at a current of 1.0 A for about 2.0 ms. Suppose a grown electric eel has 4.0 × 10 3 electrocytes and can deliver up to 3.00 × 10 2 shocks in rapid series over about 1.0 s. (a) What maximum electrical power can an electric eel generate? (b) Approximately how much energy does it release in one shock? (c) How high would a mass of 1.0 kg have to be lifted so that its gravitational potential energy equals the energy released in 3.00 × 10 2 such shocks?

Study of body parts and their functions. In this combined field of study, anatomy refers to studying the body structure of organisms, whereas physiology refers to their function.
A particular myelinated axon has nodes
spaced 0.80 mm apart. The resistance
between nodes is 20 MQ; the capacitance of
each insulated segment is 1.2 pF. What is
the conduction speed of a nerve impulse
along this axon?
An electric catfish can generate a significant potential difference using stacks of special cells called electrocytes. Each electrocyte develops a potential difference of 110 mV. How many cells must be connected in series to give the 350 V a large catfish can produce?
