Multiple Choice

Why is it a good idea for a bacterial cell to be able to utilize glucose FIRST as an energy source (until it's used up) ,THEN switch to lactose?

• A)Glucose is an easier compound to break down and obtain energy from than lactose.
• B)Lactose cannot be used by bacterial cells as an energy source.
• C)It's about conservation of energy-why expend the energy to make the extra enzymes for breaking down lactose when glucose is right there and doesn't need the extra enzymes for breakdown.
• D)Glucose provides 10x as much energy when broken down as lactose.
• E)Glucose is no easier compound to break down and obtain energy from than lactose AND It's about conservation of energy-why expend the energy to make the extra enzymes for breaking down lactose when glucose is right there and doesn't need the extra enzymes for breakdown.
