1. The second stage of aerobic respiration (one word).
2. The first stage of aerobic and anaerobic respiration.
3. An organic molecule that is broken down during respiration.
4. A type of respiration that occurs in the presence of oxygen.
5. The process utilized by some bacteria and animal cells to break down pyruvate anaerobically (one word).
6. The form of energy that cells can use. The product of respiration.
7. The end product of glycolysis.
8. Where in the mitochondria does the Krebs Cycle occur?
9. Organisms that breakdown organic molecules, like glucose, produce ATP, carbon dioxide, and water.
10. The last stage of aerobic respiration (one word).
11. A reactant of respiration that is used as an electron acceptor.
12. A type of respiration that occurs in the absence of oxygen.
13. A product of respiration that is formed when the carbons of glucose are released during the breakdown (one word).
14. Electrons from acetyl-CoA are added to NAD+ creating…
15. The process of breaking down organic molecules, like glucose, to form ATP.
16. Pyruvate is broken down into this before the Krebs Cycle begins (one word).
17. The organelle where respiration takes place in organelle containing cells.
18. Energy from the environment that can be captured through processes like photosynthesis (one word).
19. H+ ions are also called…?
20. Organisms that can produce organic molecules, like glucose, from carbon dioxide, and water.
21. Where in the mitochondria does the electron transport chain occur?
22. Where in the mitochondria does the H+ gradient build that powers ATP synthase?
23. The enzyme that converts pyruvate into acetyl-CoA.
24. The protein that utilizes H+ ion flow to produce ATP from ADP and Pi (one word).
25. A product of respiration that is formed when oxygen combines with H+ ions and electrons.
