lon channels are active pores in a cell membrane that transport ions between the cell's interior and exterior. Although generally opened or closed by various cellular mechanisms, for inert cells studied in the laboratory the pores can open or close due to thermal effects alone. In other words, we can model an ion channel as a two-state system with open energy Eopen and closed energy Eclosed. In one study, performed at 37°C. the channels were found to be open 10% of the time and closed 90% of the time. Part A A Which energy is higher: Eopen or Eclosed? Expen Eclosed Submit Part B ✓ Correct: What is the energy difference between the two states? Express your answer with the appropriate units.
