Cellular respiration
A yeast cell is transported from an environment with oxygen to a completely oxygen-free environment.
Which of the following answer choices best describes the metabolic changes that will occur in the yeast cell?
Choose 1 answer:
Glycolysis will still occur and pyruvate will undergo alcohol fermentation, but the Krebs cycle and
oxidative phosphorylation will not occur.
Glycolysis will not occur and pyruvate will not form, causing the yeast cell to undergo alcohol
fermentation.
Glycolysis will still occur, but pyruvate will not form, causing the yeast cell to undergo alcohol

- Chapter 9 L discusses some oxygen requirement, grouped. We're going to focus on those that do not necessarily need oxygen for survival. For this part: aerotolerance, categories under which most prokaryotic organisms can be 1. What oxygen requirement, or aerotolerance, categories allow for an organism to survive in the complete absence of oxygen? Please list those oxygen requirement/aerotolerance categories where an organism doesn't necessarily need oxygen for growth. 2. Oxygen is toxic to most organisms, even you! One reason we don't see the effects of this is because most organisms are able to produce enzymes to counteract this toxicity. This is called, "detoxifying reactive oxygen species (ROS)," as discussed in Chapter 9. In order to survive in the presence of oxygen (if it can), a prokaryotic organism must be able to undergo detoxification of reactive oxygen species.
