Document Summary
Sperm doesn"t have mitochondria reduced to just nucleus to get to egg. Purpose: capture energy from oxidation of nadh and fadh2 to transfer h+ across inner mitochondrial membrane. Nadh + h+ + o2 nad+ + h2o. Fadh2 + o2 fad + h2o. Reduction potential ( ): the desire to be reduced (to gain electrons) Potential to be reduced is negative (-) Negative reduction potential ( < 0) means that reaction is unfavorable . Positive reduction potential ( > 0) means that reaction is favorable . Transfer of electrons from a to b is possible (net g < 0) only if reaction potential of b is higher than that of a ( a > b) Ared + box aox + bred. Energy released from oxidation of a (- gox) must be greater than energy consumed by reduction of b ( gred) Electrons transferred from compounds with lower to compounds with higher .
