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.
Why don't obligate anaerobes require catalyse?
Because they die in the presence of catalase. They also die in the presence of oxygen, due to the absence of superoxide dismutase and catalase. It converts the lethal superoxide inside their cells due to the presence of oxygen.
Explain the toxic effect of oxygen on strict anaerobes?
Strict anaerobic organisms die in the presence of oxygen because the presence of oxygen causes them to create superoxide. Superoxide is toxic and is dismantled in aerobes and facultative anaerobes by the presence of superoxide dismutase. However, strict anaerobes do not have this enzyme, leaving the cell with an accumulation of superoxide which will kill the organism.
In an oxygen-rich environment which has a competitive advantage aerobic bacteria or anaerobic bacteria?
Aerobic bacteriaBecause some anaerobic bacteria will die in the presence of oxygen.
What are bacteria that cannot live without oxygen called?
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
Do aerobes die in the presence of oxygen?
No. Oxygen is required for respiration in aerobes.
Why do organisms die when they don't have oxygen?
organisms need oxygen because if organism didnt they would mutate into non organisms and create virus called stilia

When a organism dies how long does it take for the cells to die?
until the cells run out of oxygen
What would happen if there was no oxygen on earth?
Some Bacteria do not need and will even die in the presence of oxygen. They would thrive and probably evolve.
What is Anaerobic?
An anaerobe is an organism that grows without air. The organism can only live in oxygen-free conditions. If oxygen is present, the organism could die.
Will you die from low oxygen?
Yes, you can die from a low oxygen level, this is called anoxia.
What happens to anaerobic organism in presence of oxygen?
mostly they die. oxygen is highly reactive and creates free radicals which destroy cell membranes. by the way the very same process is killing us slowly day by day, cell by cell... take a breath :)
In an oxygen-rich environment which has a competitive advantage aerobic bacteria or anaerobic bacteria?
Aerobic bacteriaBecause some anaerobic bacteria will die in the presence of oxygen.
If the heart is diseased what will happen to the organism?
The organism will die. The heart pumps blood, which carries oxygen to all parts of the body- including the brain. If the brain is deprived of oxygen for more than 4 minutes, under most circumstances, the brain dies. When the brain dies, the organism dies.
