Across 1. in the intermediate stage, pyruvic acid loses CO2 and combines with this molecule 6. the final electron acceptor in the ETC 7. pyruvic acid moves to this organelle for the citric acid cycle 13. occurs in the cytoplasm and breaks down glucose 15. this is produced because of the difference in charge across the mitochondrion membrane 19. series of reactions that will take the acetyl CoA to form CO2, NADH and ATP 20. oxygen is required 21. there are three of these produced during one turn of the CAC 22. when oxygen react with 4 H+ it forms two molecules of this 23. which membrane does the ETC occur in

Down 2. NADH and FADH2 are examples of these types of molecules 3. number of ATP molecules needed to start glycolysis 4. the inner membrane becomes positively charged because of a buildup of these ions 5. some of the energy form the ETC is used to make this molecule 8. type of molecules in the membranes that pass the electrons 9. during glycolysis, glucose first breaks down into 2 of these molecules 10. glucose is broken down into 2 3-c molecules of this 11. number of carbons in glucose 12. besides NAD+, the other electron carrier in the CAC 14. the citric acid cycle is also called this 16. the molecule formed from coenzyme A and pyruvic acid 17. no oxygen is required 18. the number of ATP produced in the ETC
