Whether valinomycin acts as uncoupler or inhibitor of oxidative phosphorylation. Introduction : The addition of valinomycin to an actively respiring mitochondria result in various things. The production of ATP (adenosine triphosphate) is decreased and there is an increase in the consumption of O 2 (oxygen). Heat is liberated and an increase in the pH gradient across inner mitochondrial membrane is observed.

Question

Chapter 19, Problem 7P

Summary Introduction

To explain: Whether valinomycin acts as uncoupler or inhibitor of oxidative phosphorylation.

Introduction:

The addition of valinomycin to an actively respiring mitochondria result in various things. The production of ATP (adenosine triphosphate) is decreased and there is an increase in the consumption of O₂ (oxygen). Heat is liberated and an increase in the pH gradient across inner mitochondrial membrane is observed.

Summary Introduction

To explain: Experimental observation of valinomycin to transfer potassium ions.

Introduction:

The uncoupling agents are those chemical compounds which uncouple oxidative phosphorylation from electron transport chain. As a consequence of this, there occurs an increase in the consumption of oxygen; however, ATP production is decreased. The proton gradient is dissipated as heat. There is an increase in the concentration of proton outside the inner mitochondrial membrane. Valinomycin is an uncoupler.
