The Story Thus Far…

Where the Action Is Occuring

A diagram of a mitochondrion, including the matrix where all the energy-rich molecules are located. Shows the progress of cellular respiration so far, across a mitochondrial matrix	.

The Two-Step Process

1. Electron Transport

Shows the electron transport chain, from NADH and FADH_2 to O_2. A graphical representation of the use of energy from the electron transport chain to pump hydrogen ions outside the matrix.

Figure 9.13, page 158, and 9.15, page 160, Campbell's Biology, 5th Edition

2. ATP Synthesis

Shows how ATP synthase uses the motion of hydrogen ions across the matrix to convert ADP (plus an inorganic phosphate) into ATP.
