Question

question 1
many microbe species, including the yeast from this experiment, are facultative anaerobes that can metabolize sugars by both aerobic respiration and by fermentation. apply your knowledge of these processes and yeast metabolism to suggest the optimal growing conditions for facultative anaerobes to ensure maximum energy conversion during metabolism.

Explanation:

Facultative anaerobes can use both aerobic and anaerobic respiration. Aerobic respiration yields more energy. So, optimal conditions would be aerobic with an abundant supply of sugar (substrate for metabolism).

Answer:

Aerobic conditions with ample sugar availability.
