Each molecule of NADH produced in the mitochondria provides the energy for two ATP molecules.

Answer

### Step-by-Step Solution:

1. **Understanding the Role of NADH**:
- NADH is a crucial electron carrier in cellular respiration, specifically in the mitochondria. It is produced during glycolysis and the Krebs cycle.

2. **Electron Transport Chain (ETC) Overview**:
- The electron transport chain is located in the inner mitochondrial membrane and consists of several protein complexes (Complex I, II, III, and IV). NADH donates electrons to Complex I.

3. **Electron Transfer and Proton Pumping**:
- As electrons are transferred from NADH through the complexes (from Complex I to IV), energy is released. This energy is utilized to pump protons (H⁺ ions) from the mitochondrial matrix into the intermembrane space, creating a proton gradient.

4. **Formation of ATP**:
- The proton gradient generated across the inner mitochondrial membrane creates potential energy. This energy is harnessed by ATP synthase (also known as ATPase), which synthesizes ATP as protons flow back into the matrix.

5. **ATP Yield from NADH**:
- Each molecule of NADH can lead to the production of approximately three ATP molecules, not two. This is due to the efficient use of the proton gradient created during the electron transport process.

6. **Conclusion**:
- Therefore, the statement that "each molecule of NADH produced in the mitochondria provides the energy for two ATP molecules" is incorrect. The correct statement is that each NADH can produce about three ATP molecules.
