Electrons in electron transpo chain travel from:: (A) One way irrespective of the potential, (B) Low to high potential, (C) Two way, (D) High to low potential
Answer is B. Electrons in electron transpo chain travel from low redox potential to high redox potential. Redox potential is the tendency to gain electrons. In ETC, NADH has minimum R.P. (a Strong Electron Donor) and oxygen(O2)has maximum R.P. (a Strong Electron Acceptor).
