### Mitochondrial Electron Transport Adaptation2. **Unique Electron Acceptor in Mitochondrial Electron Transport**: - **Observation**: A cell is discovered to use Cu²⁺ as the final electron acceptor in mitochondrial electron transport (MET) instead of O₂. - **Reaction**: \[ \text{Cu}^{2+} + 2e^- \leftrightarrow \text{Cu}^0 \] \[ \text{E}^\circ = +0.337 \, \text{V} \] - **Problem Statement**: **A. Calculation of Free Energy**: Determine how much free energy can be gained by the oxidation of NADH in this novel MET system. Show calculations.### Detailed ExplanationThe reduction potential (Eº) for the half-reaction provided is +0.337 V for Cu²⁺/Cu⁰. To determine the free energy change (ΔG) from the oxidation of NADH, we need to use the Nernst equation and the known standard reduction potential for NADH/NAD⁺.Key Steps for Calculation:1. **Identify the standard reduction potentials**: - For Cu²⁺ + 2e⁻ → Cu⁰: Eº = +0.337 V - For NAD⁺ + H⁺ + 2e⁻ → NADH: Eº = -0.320 V2. **Calculate the overall cell potential (Eºcell)**: \[ \text{Eº} = \text{Eº (electron acceptor) - Eº (electron donor)} \] \[ \text{Eºcell} = 0.337 \, \text{V} - (-0.320 \, \text{V}) = 0.657 \, \text{V} \]3. **Use the Gibbs free energy equation**: \[ \Delta G = -nFEºcell \] where: - \( n \) = number of moles of electrons exchanged (n = 2 for NADH oxidation reaction) - \( F \) = Faraday constant (approximately 96485 C/mol) - \( Eºcell \) = total cell potential (0.657 V)4. **
