Why Is It a Good Idea for a Bacterial Cell

question 66

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 an 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.
