Define the term substrate-level phosphorylation. How does it differ from oxidative phosphorylation? What compound(s) do fermentative bacteria need to synthesize in order to make ATP by substrate-level phosphorylation?
Answer to relevant QuestionsWhat are the major fermentation products of the following bacteria: Lactobacillus, Clostridium, Propionibacterium, Escherichia? Compare and contrast acetogens with methanogens in terms of (1) substrates and products of their energy metabolism, (2) ability to use organic compounds as electron donors in energy metabolism, and (3) phylogeny. How does light result in ATP production in an anoxygenic phototroph? In what ways are photosynthetic and respiratory electron flow similar? In what ways do they differ? A fatty acid such as butyrate cannot be fermented in pure culture, although its anaerobic catabolism under other conditions occurs readily. How do these conditions differ, and why does the latter allow for butyrate ...Contrast the metabolic characteristics of acetic acid bacteria and acetogens. What characteristic do they share and in what ways do they differ?
