The cell membrane has ion channels that can exist in two states, open or closed. When they are open, they let Na+ ions through. The energy of the open state is 4*10^-20 J. higher than the state of the closed channel. a. What proportion of the ion channels are open at a temperature of 20 C? b. How high should the temperature be so that 75% of the channels are open?         Don't use Chat GPT otherwise I will report from bartleby.
