You have been growing some animal cells in culture. The cells grow well for several weeks, and then their growth slows down. You conduct some tests and determine that there is a lot of lactic acid in the culture fluid. Which of the following is the most likely explanation for the poor growth of the cells? a. There is too much glucose in the culture fluid. b. There is not enough glucose in the culture fluid c. There is too much oxygen in the culture fluid. d. There is not enough oxygen in the culture fluid

During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respiration. As a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. This alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness. Which of the following statements does the above information support? A. Cellular respiration is affected by sugar production. B. Cellular respiration is affected by cell hydration. C. Cellular respiration is affected by the availability of reactants. D. Cellular respiration is affected by temperature.

A bacterial culture, growing on glucose, is moved from aerobic growth to anaerobic growth. You know that this particular bacterium is a facultative anaerobe. a.) Under the above scenario, will the rate of glucose usage increase, decrease, or stay the same? WHY? b.) Under which condition (aerobic or anaerobic growth) will there be less CO2 produced per mole of glucose? WHY?
Suman K.
During lactic acid fermentation, which of the following events is least likely to occur? (A) An oxygen debt builds. (B) NADH is reduced. (C) Lactate accumulates in the muscle tissue. (D) ATP is produced. (E) $\mathrm{NAD}^{+}$ is recycled and returns to the Krebs cycle.
