**Energy Requirements and ATP Synthesis for Adults**

A 70 kg (154 lb) adult requires a daily calorie intake of 2,000 kcal (8,360 kJ) for proper functioning over a 24-hour period. This energy comes from metabolized food, which is converted into free energy. This energy is crucial for synthesizing ATP (adenosine triphosphate), which is used for various biological processes.

**Key Information:**
- **Caloric Conversion:** Each calorie (or "Calorie" as listed on food labels) corresponds to 1.0 kcal in biochemical terms.
- **ATP Details:** 
  - The molecular weight of ATP is 505 g/mol.
  - Each mole of ATP equates to 30.5 kJ of energy.

**Efficiency and Calculation:**
- The efficiency of converting food energy into ATP is assumed to be 50%.
- Based on this efficiency, further calculations can be conducted.

This information serves as a basis for understanding energy conversion in biochemical terms and the role of ATP in human metabolism.
