Question

To produce the same amount of cell material, would a fermenting bacterium require higher levels of sugar in its environment compared to an anaerobically respiring bacterium?

Yes/ No?

True or false questions

1.in the absence of light, Photosystem II in oxygenic photosynthesis will still produce oxygen as a waste product

2.Sporulation involves both anabolic and catabolic metabolic processes.

3.ABC type transport of the sugar fructose uses ATP.

4.ATPases are a type of protein that contributes to the fluid mosaic model.

5.There is no external electron donor used in anoxygenic photosynthesis.

6.Glycolysis alone is not a metabolism.

Answer 1

To produce the same amount of cell material, would a fermenting bacterium require higher levels of sugar in its environment compared to an anaerobically respiring bacterium?

Answer- yes

Explanation- in fermentation, it produces only 2 molecules of ATP for each molecule of glucose, while in aerobic respiration 38 ATP s are produced with each molecule of glucose. Thus anearobic bacteria requires higher amount of sugar level in environment to produce same amount of cell material as that made by aerobic bacteria.
