Across
  1. 2. Transport Chain (ETC) – A series of proteins in the inner mitochondrial membrane that pass electrons to create a proton gradient and make lots of ATP.
  2. 4. Fermentation – An anaerobic process in yeast/bacteria that turns pyruvate into alcohol (ethanol) and carbon dioxide.
  3. 5. – A 3-carbon molecule made at the end of glycolysis.
  4. 6. – The first step of cellular respiration; breaks glucose into two pyruvate molecules and makes a little ATP. Happens in the cytoplasm.
  5. 10. (Adenosine Triphosphate) – The main energy molecule of the cell.
  6. 12. Respiration – The process cells use to break down glucose and make ATP (energy).
  7. 14. – A process that does require oxygen.
  8. 17. – A 4-carbon molecule that combines with Acetyl CoA to start the Krebs cycle.
  9. 18. Cycle (Citric Acid Cycle) – A series of reactions in the mitochondrial matrix that breaks down Acetyl CoA to produce CO₂, NADH, and FADH₂.
Down
  1. 1. – A process that does not require oxygen.
  2. 3. CoA – A molecule formed when pyruvate enters the mitochondria and is prepared for the Krebs cycle.
  3. 7. Acid Fermentation – An anaerobic process that turns pyruvate into lactic acid and makes a small amount of ATP. Happens in muscle cells when oxygen is low.
  4. 8. – The innermost space of the mitochondria where the Krebs cycle happens.
  5. 9. Space – The space between the inner and outer membranes of the mitochondria; where protons build up during the ETC.
  6. 11. – The movement of protons (H⁺ ions) across a membrane that drives ATP synthase to produce ATP.
  7. 13. – Another energy-carrying molecule that transports electrons to the electron transport chain.
  8. 15. Membrane – The membrane inside the mitochondria that contains the ETC and ATP synthase.
  9. 16. – An energy-carrying molecule that delivers electrons to the electron transport chain.
