Summary Introduction

To determine: How venturicidin affects oxygen evolution in a suspension of well illuminated chloroplasts.

Introduction:

Venturicidin is an antifungal compound which inhibits the ATP synthesis from mitochondria. It inhibits the F0 present in ATP synthase enzyme and inhibits the ATP synthesis by oxidative phosphorylation mechanism.

Summary Introduction

To determine: Whether the answer change if the experiment were done in the presence of an uncoupling reagent such as 2,4-dinitrophenol (DNP).

Introduction:

Photophosphorylation could be uncoupled from the flow of electron by the uncoupling reagent like 2,4-dinitrophenol (DNP) which provides path for the proton transport through thylakoid membrane.
