Question

E. coli is a species of bacteria that, under the appropriate conditions, can grow using fermentation, anaerobic respiration, or aerobic respiration. This is one example of how E. coli has a greater metabolic capability than we humans, who can only survive using aerobic respiration, and who can perform fermentation for short periods of time. Consider the relative energy yield and efficiency of these three processes. Imagine you grow three cultures of E. coli as follows: A: Anaerobic respiration in the absence of mitochondria B: Anaerobic respiration in the presence of mitochondria C: Aerobic respiration You provide each culture with sufficient glucose in order to get each culture to produce the same biomass, i.e., the same amount of E. coli cells. In order to accomplish this, which culture would need to consume the greatest amount of glucose? A: Anaerobic respiration in the absence of mitochondria B: Anaerobic respiration in the presence of mitochondria C: Aerobic respiration Each culture would need to consume the same amount of glucose to produce the same biomass
