  24. 18. Identify substances that can be produced as a result of alcoholic fermentation. • Carbon dioxide • Ethyl alcohol (beer and wine)

  25. 19. Identify the number of ATP produced as a result of alcoholic fermentation. • 2ATP

  26. ANAEROBIC Let’s review: Choose AEROBIC or ANAEROBIC or BOTH for the statements below. • Produces 2ATP. • Utilizes oxygen. • Can occur in muscle cells when oxygen is not present. • Release lactic acid as waste. • Produces 36 ATP. • Occurs in mitochondria. • Also known as fermentation. • Release CO2 and H2O as wastes. • Can cause muscle fatigue.

  27. ANAEROBIC BOTH ANAEROBIC 10. Occurs only in the cytoplasm. 11. Glucose is a raw material. 12. Can release alcohol as a waste. 13. Most efficient. 14. Can occur in yeast. 15. Can occur in bacteria. 16. Does not use oxygen. 17. Release energy used for all life processes. AEROBIC ANAEROBIC ANAEROBIC AEROBIC AEROBIC
