The potential energy in ATP is released when the terminal high-energy bond is broken by a process called ___________________________. Write the end products of this process: ATP (+ H2O) → _________________ 3. Rebuilding ADP into ATP with a new source of energy is carried out by a process called ______________________________. Write the equation for this process: __________________ → ATP (+ H2O) 4. List the three processes used to synthesize additional ATP when ATP supplies are low: 1. _______________________________ 2. _______________________________ 3. _______________________________ 5. An immediate source of energy is _____________________ (CP), but the supplies are limited and rapidly depleted. One molecule of CP produces ___ ATP. 6.
