The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept
ATP is formed from ADP and inorganic phosphate in an energy-requiring reaction.

Step 2: Energy value
The terminal high-energy phosphate bond stores about 7.3 kcal per mole. This is the same energy released when ATP is hydrolysed to ADP and Pi.

Step 3: Conclusion
The missing value is 7.3.

Final Answer:
The missing energy is 7.3 kcal. \[ \boxed{\text{(C) }7.3} \]
