Question
Chapter 19, Problem 21P
Interpretation Introduction
Interpretation:
It is required to propose the inhibitory site of DCMU.
Concept introduction:
DCMU or Dichlorophenyldimethylurea is aherbicide that interferes with the process of photophosphorylation and oxygen evolution. In the presence of an artificial electron acceptor like ferricyanide, the oxygen evolution is not blocked.

Tease
10. Like rotenone, cyanide is a broad-spectrum poison that affects many organisms. In fact, most
poisons that act on the citric acid cycle, electron transport chain, and ATP synthase are broad-
spectrum. What does this suggest about the evolution and conservation of these pathways?
