Electrons play an important role in cellular respiration. a) Where do the electrons come from? What causes them to 'free' up? b) What molecules 'pick up' the electrons? Include 2 examples of these. c) Where do the electrons go and how do they help in the process of ATP synthesization?

part A

the electrons are usually the currently of chemical reactions

B)it returns to glycolysis to pick up more electrons

ex. gulycolysis yields 2ATP

C) they goes to Krebs cycle

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
