What is a gram-negative cell wall?
300
Organisms that can switch metabolic processes depending on whether oxygen is present or not.
What are Facultative Anaerobes?
300
Chemical control method that is an effective antimicrobial in very small amounts.

400
If a bacterium encounters a repellent in the environment, its flagella will rotate to cause a ______.
What is a tumble?
400
This enzyme is important for breaking down the toxic radical hydrogen peroxide.
What is Catalase?
400
This oxidizing agent will be ineffective if a microbe produces catalase.
What is Peroxygen?
400
If you are trying to inhibit the synthesis of peptidoglycan, you better make sure that the bacterium does not have this enzyme present.
