Across
  1. 3. without oxygen
  2. 7. crucial 4C molecule in cell metabolism, acting as a key link in the Kreb’s cycle.
  3. 8. space the narrow gap between the outer and inner membranes of a mitochondria
  4. 11. the process where ions move across a semipermeable memebrane
  5. 12. carries high-energy electrons from the Kreb’s cycle to the ETC
  6. 15. Cycle it’s the “hub” for aerobic metabolism, extracting maximum energy from food.
  7. 16. Acid Fermentation anaerobic process where cells, like muscle cells during intense exercise or certain bacteria, convert glucose into ATP and lactic acid.
  8. 17. used to generate more ATP in the presence of oxygen
  9. 18. respiration process where living cells convert nutrients and oxygen into ATP, releasing carbon dioxide and water.
Down
  1. 1. process of breaking down a glucose molecule into 2 smaller molecules of pyruvate
  2. 2. gel-like substance enclosed by the inner membrane of the mitochondrion
  3. 4. CoA molecule that acts as a central hub in metabolism, formed from the breakdown of carbohydrates, fats, and proteins
  4. 5. with oxygen
  5. 6. membrane narrow region between the inner and outer membrane of a mitochondria
  6. 9. molecule that helps enzymes work
  7. 10. vital series of proteins in cells that help convert energy into ATP, involving the movement of electrons
  8. 13. main molecule cells use to provide energy for their functions
  9. 14. Fermentation anaerobic process where yeast or bacteria convert sugars into ethanol and carbon dioxide
