Textbook Question
Chapter 23.1, Problem 1MI
The presence of an electron transport chain in a strictly fermentative microbe is unusual. Describe how this microbe uses its ETC and how this differs from a respiratory microbe.

Students have asked these similar questions
What is one difference between fermentation and anaerobic respiration? Since neither requires oxygen, why would a microbe select one of these versus the other? Name a specific microbe which uses fermentation and a specific microbe which uses anaerobic respiration.
A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules.
How does this organism make NADH?
Oxygen is always beneficial to micro-organisms. Discuss this statement in the context of factors that influence microbial growth.
