A) difficult for biological systems to capture.
B) usually lost as heat.
C) less than the energy needed by the reverse reaction of ADP + P_i $\rightarrow$ ATP.
D) more than the energy needed by the reverse reaction of ADP + P_i $\rightarrow$ ATP.
E) equal to the energy needed by the reverse reaction of ADP + P_i $\rightarrow$ ATP.
