Kreb Cycle

2. – A two-carbon molecule that enters the Krebs cycle to begin energy production.
5. – Another electron carrier formed in the Krebs cycle that transports energy to the electron transport chain.
7. – A protein that speeds up chemical reactions in the Krebs cycle.
9. – A four-carbon molecule that reacts with acetyl-CoA to start the Krebs cycle.
11. – A compound formed during the Krebs cycle that later converts into fumarate.
13. – The main energy molecule of the cell, generated during cellular respiration.
14. – A molecule produced and used during different steps of the Krebs cycle.
15. – A high-energy electron carrier produced during the Krebs cycle and used in the electron transport chain.

1. – The end product of glycolysis that is converted into acetyl-CoA before entering the Krebs cycle.
3. – The first compound formed in the Krebs cycle when acetyl-CoA combines with oxaloacetate.
4. – An intermediate compound in the Krebs cycle formed after isocitrate loses carbon dioxide.
6. – A four-carbon molecule that is converted back into oxaloacetate to complete the cycle.
8. – The powerhouse of the cell where the Krebs cycle takes place.
10. – The main output of the Krebs cycle in the form of ATP, NADH, and FADH₂.
12. dioxide – A waste product released during the Krebs cycle when carbon atoms are removed from molecules.
