In the electron transport chain, electrons are transferred from Complexes I and II to Complex III via _____. The electrons from Complex III are transferred to Complex IV via _____. O2 is reduced to H2O at _____.
Coenzyme Q. ,Cytochrome C ,mitochondrial matrix
COQ is an organic molecule . The CoQ receives the electrons from the Complex - l and the Complex - ll and it passes the electrons to the Complex - Ill .
cytochromes are water soluble carriers imbedded in the mitochondrial membrane . The mobile cytochrome electron carrier in mitochondria is cytochrome c
The water molecules are produced in mitochondria , in the electron transport system , when the electrons exit the final electron carrier of the respiratory chain in the inner mitochondrial membrane and are accepted by molecular oxygen , along with the binding of hydrogen ions to form H20 .
