Question 16 Electron transfer between redox centers in proteins is controlled by electron tunneling. We can model the region between two redox center as an energy barrier which the electron must cross. If the distance between the redox centers is 0.531 nm and the energy of the electron is 0.212eV lower than the height of the barrier, what is the probability that the electron will successfully cross to the next redox center? Note: to enter a number like 1 x...
