February 17 Biology Harvesting Energy. Cells get energy from the food we eat. Extract energy stored in food molecules to make ATP that the cell can use to do work. Aerobic energy harvesting = cellular respiration requires oxygen complete breakdown of glucose glucose in the presence of oxygen will produce water, carbon dioxide, and energy (which can be used to make ATP) four phases in cytoplasm and mitochondria Anaerobic energy harvesting = fermentation does not require oxygen incomplete breakdown of glucose two phases in cytoplasm lactic acid fermentation = basically a waste product that the body can recycle Which of the following is a difference between aerobic and anaerobic energy harvesting? a. aerobic uses oxygen; anaerobic makes oxygen b. aerobic occurs only in mitochondrion; anaerobic occurs only in cytoplasm c. aerobic makes ATP; anaerobic makes sugar d. aerobic makes CO2; anaerobic does not e. aerobic occurs only in eukaryotic cells; anaerobic occurs only in prokaryotic cells Aerobic vs. Anaerobic requires O 2 does not require O 2 4 phases 2 phases cytoplasm only 36 ATP/glucose 2 ATP/glucose glucose → CO 2 glucose → 3C Cell Division = reproduction of cells
