Question

Catabolic Energy Generating Mechanism 3a. You are working with a nitrate-oxidizing aerobic bacteria that contains the enzymes necessary to run the Calvin cycle What classification of organism would these bacteria be? What molecule would it use as an electron donor? An electron acceptor b. You find tha concentrations are low. Why could this be beneficial to the organism is the lo t the organism above has a second electron transport chain that utilizes hydrogen oxidation when oxygen w oxygen environment? 4. Zymomonas mobillsis one of the only organisms that can only metabolize glucose through the Entner-Doudoroff pathway and does not contain any type of electron transport chain. I purpose of fermentation for this bacteria? Instead, it utilizes ethanol fermentation. Explain the b. Interestingly, the alcohol industry has considered using Zymomonas instead of yeast in alcohol production because it uses glucose and produces a higher concentration of ethanol at a fa use the Embden-Meyerhof pathway for its glucose metabolism. How does th utilization and ethanol production difference between the two organisms? ster rate. Standard Saccharomyces cerevisioe yeast is helps explain the rate of glucose

Explanation / Answer

3a- This bacterium species is a nitrifying bacterium and comes under Phylum Proteobacteria.

The electron donor will be ammonia molecule. That electron will then finally accept by the Oxygen molecule to make water molecule.

3b- That would be great if we have such bacteria because maximum known species are aerobic. This is good for those areas where oxygen is low. For example, plants in Hill area that cannot easily uptake nitrogen, these bacteria can perform well to help in developing plants.
