3. (4 pts) Living organisms use energy from the metabolism of food to create an energy-rich molecule called adenosine triphosphate (ATP). The ATP then acts as an energy source for a variety of reactions that in living organisms must carry out to survive. ATP provides energy through its hydrolysis, which can be symbolized as follows: ATP(aq) + H2O(l) → ADP(aq) + Pin(aq) &Gorun =-30.5 kJ where ADP represents adenosine diphosphate and Pm represents an inorganic phosphate group (e.g., HPO,). In...
