Question

13 when might you experience lactic acid fermentation in your cells? 14 how does the atp production differ in aerobic and anaerobic respiration? 15 what are the two types of fermentation processes? what does each produce? 16 what process is common to both aerobic and anaerobic respiration? where does this process occur in the cell?

Explanation:

1. Lactic - acid fermentation occurs when the body needs quick energy during intense exercise and oxygen supply is limited.
2. In aerobic respiration, a large amount of ATP (30 - 32 ATP per glucose) is produced through oxidative phosphorylation. In anaerobic respiration (like lactic - acid or alcoholic fermentation), only 2 ATP per glucose are produced during glycolysis as the process does not proceed to the more energy - yielding steps that require oxygen.
3. The two types of fermentation are lactic - acid fermentation and alcoholic fermentation. Lactic - acid fermentation produces lactic acid and 2 ATP, while alcoholic fermentation produces ethanol, carbon dioxide, and 2 ATP.
4. Glycolysis is common to both aerobic and anaerobic respiration. It occurs in the cytoplasm of the cell.

Answer:

1. During intense exercise with limited oxygen supply.
2. Aerobic respiration produces 30 - 32 ATP per glucose, anaerobic respiration produces 2 ATP per glucose.
3. Lactic - acid fermentation produces lactic acid and 2 ATP; alcoholic fermentation produces ethanol, carbon dioxide, and 2 ATP.
4. Glycolysis; cytoplasm.
