WebbThe pH of the mitochondrial matrix is ca. 8. Thus, [H +] = 10 -8 M (moles per litre). If the mitochondrial volume is 0.2 μm 3 this is equivalent to 2x10 -10 μl = 2x10 -16 litre Using Avagadro’s number as 6x10 23 it follows that: Total number of protons in the matrix of a mitochondrion = 10 -8 x 2x10 -16 x 6x10 23 WebbThe key steps of this process, shown in simplified form in the diagram above, include: Delivery of electrons by NADH and FADH _2 2 . Reduced electron carriers (NADH and FADH _2 2 ) from other steps of cellular respiration transfer their electrons to molecules near the beginning of the transport chain. In the process, they turn back into NAD ^+ +
