10. Slide 10 Krebs Cycle NADH ATP ADP + P i INNER COMPARTMENT OUTER COMPARTMENT acetyl-CoA free oxygen 6 H + flows back into inner compartment, through ATP synthases. Flow drives ATP formation. 1 Pyruvate from cytoplasm enters inner mitochondrial compartment. 3 NADH and FADH 2 give up electrons and H + to electron transfer chains. 2 Krebs cycle and preparatory steps: NAD + and FADH 2 accept electrons and hydrogen. ATP forms. Carbon dioxide forms. 5 Oxygen accepts electrons, joins with H + to form water. 4 As electrons move through the transfer chains, H + is pumped to outer compartment. Figure 8.5c Page 138
