Chapter 19, Problem 15E

Summary Introduction

To predict: Whether ATP or NADPH production be affected by the addition of myxothiazol to a suspension of chloroplast which is exposed to light.

Concept introduction:

The third complex in the electron transport chain known as Cytochrome bc₁ complex or Coenzyme Q – Cytochrome c reductase plays an important role in the biochemical production of ATP. Myxothiazol can act as an inhibitor of the mitochondrial Cytochrome bc₁ complex. The Complex III is a multisubunit transmembrane protein that is encoded by both nuclear genomes and mitochondrial (cytochrome b).
