WebThe effects of gymnochrome A were tested on the electrical activity of the frog atrial heart muscle. Gymnochrome A (1-5 µM) did not alter the resting potential. Gymnochrome A (5 µM) slowed the initial depolarizing phase of the spontaneously beating action potential. Under voltage-clamp conditions gymnochrome A (5 µM) did not affect the electrical …
WebThe recording electrode initially measures a potential of -60 mV (the resting potential). At some point in time (time 0), the switch is closed. The switch closure occurs instantaneously and as a result of the instantaneous closure, instantaneous current flows through the circuit.
