- 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. For each category you listed in 1), please provide: A. the enzymes that may be lacking/missing in order to detoxify…arrow_forwardApicomplexans evolved from a photosynthetic ancestor and have the remnant of a chloroplast.

They have limited numbers of ribosomes so protein production is slow. They cannot fully metabolize carbohydrates and must rely on fermentation. They lack a cell wall and are extremely fragile. The mycolic acid in their cell walls requires signification metabolic investment. Their low tolerance for oxygen retards their growth.arrow_forward
