Question

A glucose fed yeast cell is moved from an aerobic environment to an anaerobic one. If the cell continues to ATP at the same rate, how will its rate of glucose consumption compare to consumption in the aerobic environment? What color of light would be least effective at driving and why? Explain and support your answer with any necessary data. A starving cell has reached the stage where all of the ATP has been used up. If this cell was placed in a fresh nutrient at this point, will the cell recover and survive? Explain! Biologists refer to the movement of energy through an cosystem as "energy flow'' and not "energy cycling". Why do you think they use the word flow instead of cycling? Relate your answer to the laws of thermodynamics. A series of enzymes catalyze the reaction X rightarrow Y rightarrow Z rightarrow A. A binds to the enzyme that converts X to Y at a remote from its active site. This binding decreases the for the enzyme. Explain this system and what function substrate, product, and enzymes serves in this system. Use appropriate terminology.

Explanation / Answer

When the cell is fed glucose and it is in aerobic environment then the aerobic respiration occurs and in aerobic respiration 38ATPs are produced per glucose. When the yeast is shifted to an anaerobic environment them fermentation occurs and in fermentation only 2 ATPs are produced per glucose molecule. Now if the cell wants to generate 19 times more ATPs than it could produce then the rate of consumption of glucose for yeast cell will be 19 times higher than that of aerobic respiration condition's consumption rate.
