Chapter 12, Problem 12.111EP

(a)

Interpretation Introduction

Interpretation: To determine the number of protons that cross the inner mitochondrial membrane at the complex I when two electrons from an NADH molecule are passed through the electron transport chain.

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.

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.
