The enzymes that deal with toxic oxygen containing molecules are?
Antioxidant enzymes like superoxide dismutase, catalase, and glutathione peroxidase help to neutralize toxic oxygen-containing molecules, such as superoxide radicals and hydrogen peroxide, by converting them into less harmful substances. These enzymes are crucial in protecting cells from oxidative damage and maintaining proper cellular function.
Do obligate anaerobes express superoxide dismutase?
No, obligate anaerobes do not express superoxide dismutase. This is because these organisms do not encounter oxygen in their natural environment and therefore do not need enzymes to detoxify reactive oxygen species like superoxide.
What enzymes are involved in breaking down toxic products from aerobic respiration?
In aerobic respiration glucose is broken down to release energy and the only toxic products formed are carbon dioxide CO2 and apart from that excess water and it is not difficult to get rid of these things.This is called excretion (removal of toxic waste products of metabolism.)
What is the function of superoxide dismutase?
Superoxide dismutase is an enzyme that plays a crucial role in protecting cells from damage caused by reactive oxygen species. It catalyzes the conversion of the superoxide radical into oxygen and hydrogen peroxide, reducing oxidative stress and maintaining cellular health.
What is the significance of SOD and catalase to the pathogenesis of bordetella pertussis?
SOD converts the dangerous superoxide radical to hydrogen peroxide, which catalase converts to harmless water and oxygen. Catalases are some of the most efficient enzymes found in cells; each catalase molecule can convert millions of hydrogen peroxide molecules every second.
The toxic super oxide ion is converted to harmless oxygen by two enzymes?
The two enzymes that convert the toxic superoxide ion to harmless oxygen are superoxide dismutase and catalase. Superoxide dismutase converts superoxide into hydrogen peroxide, and catalase then breaks down the hydrogen peroxide into water and oxygen. This process helps to protect cells from oxidative damage.
What two enzymes are present in obligate aerobes but lacking in obligate anaerobes?
Catalase and superoxide dismutase are two enzymes that are present in obligate aerobes but lacking in obligate anaerobes. These enzymes help in breaking down toxic reactive oxygen species that are produced during aerobic respiration.

These enzymes are crucial in protecting cells from oxidative damage and maintaining proper cellular function.
What is the substrate of superoxide dismutase?
The substrate of the superoxide dismutase is the superoxide ion. The superoxide ion is believed to be responsible for the peroxidative hemolysis and lipid peroxidation.
What toxic forms of oxygen is improperly paired with the detoxifying enzyme or molecule?
Superoxide (O2-) is improperly paired with catalase, as catalase is more effective against hydrogen peroxide (H2O2). Nitric oxide (NO) is improperly paired with superoxide dismutase (SOD), as SOD mainly targets superoxide.
A microorganism that does not have a catalase or superoxide dismutase would find it difficult to live in an environment with A carbon dioxide B oxygen c high salt D temperatures above 37C?
oxygen
What enzyme detoxify oxygen?
Superoxide dismutase (SOD) and catalase are enzymes that help detoxify oxygen by converting harmful oxygen radicals into less toxic molecules like water and oxygen.
How can that lactic acid bacteria can grow aerobically although they are catalase negative?
Lactic acid bacteria can grow aerobically despite being catalase negative because they possess alternative mechanisms for dealing with reactive oxygen species generated during aerobic metabolism, such as superoxide dismutase and peroxidases. These enzymes help to detoxify harmful reactive oxygen species, allowing the bacteria to survive and grow in the presence of oxygen without the need for catalase activity.
Do obligate anaerobes express superoxide dismutase?
No, obligate anaerobes do not express superoxide dismutase. This is because these organisms do not encounter oxygen in their natural environment and therefore do not need enzymes to detoxify reactive oxygen species like superoxide.

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.
What is the relation of superoxide dismutase and catalase to the pathogeneisis of bordetella pertussis?
Bordatella pertussis is an obligate aerobe. An obligate aerobe requires oxygen for growth. It must have two essential chemicals in order to use oxygen: superoxide dismutase (SOD) and catalase. This is because oxygen in its O2- form is toxic because it has a free radical (a free-floating electron). In order for it to be useable by life, this superoxide must be counteracted by naturally occurring antioxidants, in this case SOD. SOD takes O2- and yields H2O2 and O2 . The role of catalase is then to further reduce H2 O2 into H2 O and O2.Bordatella Pertussis contains both of these enzymes, which makes them especially feisty in the human respiratory system. Phagosomes and lysosomes that our own immune system sends to combat an infections use superoxides and hydrogen peroxide their primary weapons for destroying a cell once it has been phagocytosed. But with SOD and catalase, Bordatella pertussis can break those down and essentially disarm its attackers. 11Steed 2104
