Chapter 12, Problem 12.109EP

Interpretation Introduction

Interpretation: To determine the number of protons that cross the inner mitochondrial membrane when an NADH molecule is oxidized.

Concept introduction: Oxidative phosphorylation is the biochemical process for the synthesis of ATP from ADP and ${\text{P}}_{\text{i}}$. The energy required for the synthesis is transferred from the electron transport chain.

$\text{NADH}$ is the reduced form of nicotinamide adenine dinucleotide. It is employed as an oxidizing agent in various reactions like oxidation of secondary alcohol into a ketone. Its structure consists of three subunits: nicotinamide, ribose, and ADP.
