Cellular Respiration

1. This process occurs in the mitochondria when oxygen is available and produces the most ATP.
3. The first step of cellular respiration that occurs in the cytoplasm.
5. The molecule that is oxidized in glycolysis to generate NADH.
7. The cycle that occurs in the mitochondrial matrix, producing ATP, NADH, FADH₂, and CO₂.
8. The final electron acceptor in the ETC.
9. The waste product expelled from the body during cellular respiration after the Krebs cycle.
10. Type of respiration that does not require oxygen and produces a small amount of ATP.
13. The molecule that is produced in fermentation and used to regenerate NAD⁺ in anaerobic conditions.
14. Molecule that provides energy for cells, produced by glycolysis, the Krebs cycle, and the ETC.
15. Byproduct formed when oxygen and electrons combine at the end of the ETC.

2. Location of glycolysis in the cell.
4. Where the electron transport chain occurs.
6. Glucose is broken down during this process.
11. This molecule is produced in alcohol fermentation and is used in beer and wine production.
12. This step happens between glycolysis and the Krebs cycle and involves conversion of pyruvate into Acetyl-CoA.
