  • Upon fertilization, the eggs of many species undergo a rapid change in potential difference across their...

    Upon fertilization, the eggs of many species undergo a rapid change in potential difference across their outer membrane. This change affects the physiological development of the eggs. The potential difference across the membrane is called the membrane potential, Vm, which is the potential inside the membrane minus the potential outside it. The membrane potential arises when enzymes use the energy available in ATP to expel three sodium ions (Na+) actively and accumulate two potassium ions (K+) inside the membranemaking the...

    A high fever can interfere with normal neuronal activity. Since temperature is one of the terms in this equation (membrane potential = RT/ZF ln ([ion]in/[ion]out)) [R = 8.3145 J/K·mol; F = 96,485 J/V·mol], which defines membrane potential, a fever could possibly alter a neuron’s resting potential. 1. Calculate the effect of a change in temperature from 98.6°F to 105.8°F (37°C to 41°C) on a neuron’s membrane potential. Assume that the normal resting potential is -70mV and that the distribution of...
