Question

4) Fill in the following table: Oxygen DETOXIFYING ENZYMES Superoxide Catalase? dismutase? CLASSIFICATION ENERGY obtained by (Cellular respiration &/or fermentation) Requires/tole rates/inhibits prefers Obligate Aerobe Obligate anaerobe Facultative anaerobe Aerotolerant anaerobe Microaerophile 5) Match the following patterns of growth with the classification of bacteria. Growth throughout tube, equally distributed Growth throughout tube, heavier at top Growth at very top only Growth at very bottom only Growth at a defined spot, towards the top, but not at the very top

Answer 1

Classification	Oxygen condition	Energy obtained	Superoxide dismutase?	Catalase?
Obligate Aerobe	Requires	Cellular respiration	Yes	Yes
Obligate Anaerobe	Doesn't require	Fermentation	No	No
Facultative anaerobe	Prefer oxygen	Cellular respiration and Fermentation	Yes	Yes
Aerotolerant anaerobe	Tolerates	Fermentation	Yes	No
Microaerophile	Requires	Cellular respiration	Yes	No

Aerotolerant anaerobe grows throughout the tube, equally distributed.

Facultative anaerobe grows throughout the tube, heavy at the top.

Obligate Aerobe grows ate very top only.

Obligate Anaerobe grows at veery bottom only.

Microaerophile grows at a defined spot, towards the top, but not at the very top.
