Some species of bacteria that live at the surface of sediment on teh bottom of lakes are capable of using either glycolysis plus fermentation or cellular respiration to generate atp. there is very little circulation of water in lakes during the summer. predict and explain what will happen to the bottom most water of lakes as the summer progresses, and describe how this situation will affect energy production by bacteria.

Explanation:

As summer progresses there will be low movement or circulation of water in lakes, thus bacteria living on the surface of sediments at the bottom of lakes will not have access to enough oxygen due to poor water circulation. The bottom part of the lake will be anaerobic with little or no oxygen supply. Bacteria in the bottom of the lake cannot generate energy through cellular respiration, they will have to resort to glycolysis plus fermentation resulting lactate which is converted to pyruvate which then goes into the TCA cycle for energy generation. This process is usually more energy consuming than circular respiration and aerobic glycolysis.

answer: blah
