what is one of the main effects of mycolic acid on bacteria that possess this content
- A) Mycolic acid severely affects the nutrient uptake
- B) Mycolic acid severely affects the oxygen uptake
- C) Mycolic acid Severely affects the motility of the bacteria
- D) Mycolic acid severely affects the staining properties of the bacteria
- E) Both A and D
Answer
- D) Mycolic acid severely affects the staining properties of the bacteria
Explanation:
Mycolic acids are an important factor in bacteria and specifically for M.tuberculosis, for its unique properties that defy medical treatment aiding in the survival of the organism. Organisms with mycolic acids are resistant to chemical damage and hence resistant to normal staining procedures, and limits effectiveness of antibiotics and biocides.
Question:
choose which one is mismatch
identify the mismatch
A.) vegatative cells: actively Metabolizing cells
B.) Endospore: Dormat structure
C.) Vegetative cells: Dehydrated cells
D.) Endospore: None-reproducing structure
Answer
- ) Vegetative cells: Dehydrated cells
Explanation:
Vegetative cells are actively dividing and metabolizing, consuming nutrients and producing waste products.
Endospore is non reproductive and dormant structure produced by organisms such as bacteria to ensure survival in harsh environment.
Vegetative cells are not dormant nor dehydrated, the spores are dehydrated.
