In what situation does anaerobic respiration takes place?
When there is no oxygen, or the organism cannot use oxygen for respiration.
Why would an organism use fermentation instead of respiration?
a lack of oxygen
What is an organism that can survive with or without oxygen?
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
What is an oxygen loving organism?
Oxygen loves most metals
What organism transports oxygen?
The lungs take oxygen into the body and the blood transports oxygen throughout the body.
What is the primary use of deep?
Agar deeps are used to see whether an organism requires oxygen to grow. If there is spreading growth only at the bottom of the tube, the organism is an obligate anaerobe (meaning it cannot tolerate oxygen). If there is growth only at the surface of the agar, the organism is an obligate aerobe (it cannot grow without oxygen). And if there is growth all along the point of innoculation, the organism is a facultative anaerobe and can survive either way.
In which process is oxygen by an organism?
Respiration.
How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
. How do aerobic bacteria differ from anaerobic bacteria?
aerobic bacteria use oxygen based respiration, anaerobic bacteria use either nonoxygen based respiration (e.g. nitrogen, sulfur) or fermentation.
Can an aerobic organsm be oxidase negative?
No, the aerobic organism cannot be oxidase negative. This is because the aerobic organisms use oxygen as the electron acceptor. The aerobic organism are therefore oxidase positive.
What is having to do without oxygen?
When a process or organism doesn't require oxygen it is called anaerobic, or sometimes facultatively anaerobic depending on the specific organism. Another term for without oxygen is anoxic.
What happens if an organism performs cellular respiration without oxygen?
Anaerobic respiration does not involve oxygen.
