Cellular Respiration Across 2. Occurs in the cytoplasm and splits glucose into pyruvic acid 5. Space inside the folds of the inner mitochondrial membrane 8. Unit used to measure energy 9. The final acceptor of electrons and hydrogens in the electron transport chain 11. Inner folds of the mitochondria 13. Type of compounds broken down during cellular respiration 14. First six-carbon molecule produced in the Krebs cycle 17. Forms when pyruvic acid reacts with the enzyme CoA Down 1. Gas needed for aerobic cellular respiration 3. Compound made during anaerobic fermentation in muscle cells 4. Biochemical pathway that completes the breakdown of glucose in the mitochondria 6. Energy molecule used by cells 7. Organelle where cellular respiration takes place 10. Glycolysis and fermentation are this type of process 12. An energy carrier that transport less energy than NADH but more than ATP 14. Gas produced from the break down of glucose by organisms 15. Produced during fermentation by yeast cells 16. Energy carrier produced during glycolysis
