Cellular Respiration Crossword

3. The final electron acceptor in aerobic respiration, forming water as a byproduct.
4. A subatomic particle involved in redox reactions during cellular respiration, transferred through the electron transport chain.
5. Synthase An enzyme that synthesizes ATP by using the proton gradient generated in the electron transport chain.
6. An electron carrier similar to NADH, formed in the Krebs cycle and used in the electron transport chain.
7. The movement of protons across a membrane to generate ATP through ATP synthase.
10. Acid A byproduct of anaerobic fermentation in muscle cells when oxygen is limited.
11. A biochemical cycle occurring in the mitochondria that breaks down acetyl-CoA, releasing CO₂ and transferring electrons to carriers.
12. Organelles in eukaryotic cells where aerobic respiration occurs, generating ATP.
13. Energy carrier molecule used by cells for storing and transferring energy.
14. A protein that catalyzes (speeds up) biochemical reactions, such as those in cellular respiration.
16. An anaerobic process that generates ATP without oxygen, producing byproducts like lactic acid or ethanol.
19. A A coenzyme that aids in the formation of Acetyl-CoA from pyruvate.

1. The process of breaking down glucose into pyruvate, producing a small amount of ATP.
2. A three-carbon compound produced from glucose during glycolysis.
5. A molecule formed from pyruvate that enters the Krebs cycle for further breakdown.
8. Phosphorylation The production of ATP by directly transferring a phosphate group from a substrate to ADP.
9. Acid Cycle Another name for the Krebs cycle, a series of reactions that generates electron carriers and ATP.
15. Gradient A difference in proton concentration across the mitochondrial membrane, used to drive ATP production.
17. An electron carrier that stores high-energy electrons during glycolysis and the Krebs cycle.
18. Phosphorylation The process of ATP production in the electron transport chain, using oxygen as the final electron acceptor.
