Question

what are the end products of lactic acid fermentation? oxygen and glucose ethanol and carbon dioxide lactic acid and a small amount of atp water and carbon dioxide

Explanation:

• Option "oxygen and glucose": Oxygen and glucose are reactants (or involved in other processes like photosynthesis for glucose production), not products of lactic acid fermentation.
• Option "ethanol and carbon dioxide": These are the products of alcoholic fermentation, not lactic acid fermentation.
• Option "lactic acid and a small amount of ATP": Lactic acid fermentation occurs in the absence of oxygen (anaerobic respiration in some organisms like muscle cells in humans). Glucose is broken down, and the end products are lactic acid along with a small amount of ATP (energy) generated during the process.
• Option "water and carbon dioxide": These are the products of aerobic respiration (when oxygen is present), not lactic acid fermentation.

Answer:

lactic acid and a small amount of ATP
