MCAT Question of the Day | MCAT Course

  • Q:

    A bacterium is being studied by a scientist who discovers that oxygen is lethal to the bacterium. Which of the following best explains the reason for this?



    The ATP produced by the organism's metabolism from exposure to oxygen floods the cell to overdose.


    The oxygen is consumed by oxygen-detecting metabolic reactions which induce bacterial suicide.


    The bacterium lacks enzymes for catalyzing reactive oxygen species into more benign compounds.


    The normal energy-producing reactions of the bacterium are outcompeted by the presence of oxygen and the cell is no longer able to produce energy.
