Cellular Respiration

4. Main energy currency of the cell
6. Toxin that blocks the final transfer of electrons in the electron transport chain, leading to cell death
10. Location in the cell where glycolysis takes place
11. The six-carbon sugar that starts glycolysis
12. Where are the 2nd and 3rd steps located
13. Another name for the Krebs cycle
15. Molecule that has the capacity to generate 2 ATP molecules when it transfers its electrons to the ETC
17. The method by which H+ ions are transported from the mitochondrial matrix to the intermembrane space in the ETC
20. Electron carrier that donates electrons to the electron transport chain Electron carrier similar to NADH but with slightly less energy
21. Process that regenerates NAD+ in the absence of oxygen
22. Process of adding a phosphate group to ADP to form ATP
23. The process by which an amino group is removed from an amino acid, allowing its carbon skeleton to enter cellular respiration
24. Final electron acceptor in the electron transport chain

1. End product of glycolysis, which enters the mitochondria in aerobic respiration
2. The method by which H+ ions are transported from the intermembrane space to the mitochondrial matrix in the ETC
3. Organelle where aerobic respiration takes place
5. Molecule formed as a product of the electron transport chain when oxygen accepts electrons
7. The process by which fatty acids are broken down into two-carbon units for entry into the Krebs cycle
8. Byproduct of anaerobic respiration in muscle cells
9. Fats and amino acids enter cellular respiration in the form of this two-carbon molecule
11. First stage of cellular respiration that occurs in the cytoplasm
14. Gas released as a byproduct during the Krebs cycle and transfer step
16. Enzyme that uses the hydrogen ion gradient to synthesize ATP
18. The Krebs cycle produces enough energy to generate this many ATP molecules per glucose molecule
19. The two-carbon molecule formed from pyruvate in the transfer step
