1. Would ATP be the energy currency of the cell if the phosphate groups the cell contains were not charged? Why or why not?
2. Phosphofructokinase is an enzyme involved in glycolysis, which is a
metabolic pathway involved in ATP production. It can be allosterically
regulated by both ATP and ADP. Why is regulating the activity of this
enzyme important? Predict what will happen to the rate of reaction when
ATP levels in the cell are high, and predict what will happen when the
levels of ADP in the cell are high.
