Respiration in a bacterium is interrupted, so ADP and phosphate are no longer joined to make ATP. Before the interruption, the bacterium was taking in a substance by active transport.
Which statement explains what will happen to the rate of active transport after a short time?
The rate stays the same because energy from glucose can power active transport directly.
The rate decreases because ATP broken down during active transport cannot be replaced.
The rate decreases because ADP and phosphate can no longer be broken down to release energy.
The rate stays the same because active transport joins ADP and phosphate to replace ATP.
