Suppose that a cell’s demand for ATP suddenly exceeds its supply of ATP from cellular respiration. Which statement correctly describes how this increased demand would lead to an increased rate of ATP production? a)ATP levels would fall at first, decreasing the inhibition of PFK and increasing the rate of ATP production. b)ATP levels would rise at first, decreasing the inhibition of PFK and increasing the rate of ATP production. c)ATP levels would fall at first, increasing the inhibition of PFK and increasing the rate of ATP production. d)ATP levels would rise at first, increasing the inhibition of PFK and increasing the rate of ATP production.
