Summary Introduction
To explain:
The following observation in light of the redox tower: Escherichia coli cells fermenting glucose grow faster when nitrate (NO3-) is supplied to the culture and then grow even faster when the culture is aerated.
Concept introduction:
An oxidation is a process in which electrons are removed from a substance and in the reduction process; electrons are added to the substance. The combination of these processes is termed as redox (
