D. "The balanced equation for lactic acid fermentation is C6H12O6 → 2C3H6O3."

Answer 1

Lactic acid fermentation is represented by the equation C6H12O6 → 2C3H6O3. This process occurs in certain bacteria, such as those in yogurt, and in animals' muscles during oxygen depletion.

Step-by-step explanation:

Lactic acid fermentation is represented by the equation C6H12O6 → 2C3H6O3. This process occurs in certain bacteria, such as those in yogurt, and in animals' muscles during oxygen depletion.

During lactic acid fermentation, pyruvic acid + NADH → lactic acid + NAD+. This chemical reaction is a key step in the energy production of mammalian red blood cells and skeletal muscles that do not have sufficient oxygen to perform aerobic respiration.

This type of fermentation is used by bacteria in yogurt and by muscle cells that are working intensively. Lactic acid fermentation does not produce carbon dioxide, unlike alcoholic fermentation.
