What is reverse electron transport and why is itnecessary in purple sulfur bacteria?
When pure reduced cytochrome c is added to carefully prepared mito-
chondria along with ADP, P, antimycin A, and oxygen, the cytochrome c
becomes oxidized, and ATP is formed, with a P/O ratio approaching 1. Why
was antimycin A added, and what does this experiment tell you about the
location of coupling sites?
A denitrifying bacterium is strictly anaerobic. However, it possesses an electron
transport chain allowing « respiration ». The final acceptor is nitrate (NO3) that is
reduced in nitrite (NO₂). The electrons are introduced in the chain by the reduced
nicotinamide adenine dinucleotide coenzyme (NADH + H*).
1- Write the net reaction of the electron transport chain used by the bacterium.
2- Calculate the corresponding standard Gibbs (free) energy of reaction.
3- Is the anaerobic respiration (using nitrate) more or less exergonic than the aerobic
respiration (using O₂)? Justify your answer with numerical values.
