to prevent the build up of hydrogen peroxide
Functions of catalase
is a common enzyme found in nearly all living organisms that are exposed to oxygen where it functions to catalyze the decomposition of hydrogen peroxide to water and oxygen.

∙ 13y agosome organisms produce hydrogen peroxide as a result of respiration. accumulation of this could be toxic to the cell therefore catalase is used to degrade it into less harmful compounds like water and gaseous oxygen
Wiki User
∙ 10y agoThese are enzymes produced by aerobic bacteria in order to protect the bacteria from toxic superoxide ions that accumulate in the presence of oxygen.
Superoxide dismutase converts the superoxide ion to hydrogen peroxide, which is converted to water and oxygen by catalase and peroxidase.

Are Chryseobacterium Catalase plus or Catalase negative?
Catalase +
Did the addition of acid increase or decrease the activity of catalase?
Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It requires an optimum pH of 7 to properly function, thus the addition of acid will decrease or deactivate the enzyme.
Reaction of Bacillus Megaterium in a catalase test?
Most Bacillus species are Catalase positive.
How would you test to see if catalase could catalyze starch?
Amylase is an enzyme and, like most enzymes, it will denature when exposed to high temperatures. Denature means to lose its shape and an enzyme such as amylase is dependent on its shape to perform its function.
Does Beef Have Catalase?
Beef comes from cows and cows have catalase in their liver, so yes
Why does addition of H2SO4 stop reactions?
H2SO4 is an acid, so when you add that to the catalase reactions, the pH drops below where the catalase can function. Acids have lower pH and therefore the catalase can no longer function, so the reaction stops.
Hydrogen peroxide degradation in a cell is a function of?
Catalase and/or Peroxiredoxins
What is the point of boiling a catalase?
boiling catalase denatures the enzyme making unable to function
How does temperature affect the function of catalase?
Temperature affects the speed of the reaction and how fast the catalase reacts. Higher temperatures cause faster reactions, lower temperatures cause slower reactions.
Are Chryseobacterium Catalase plus or Catalase negative?
Catalase +
What two groups of bacteria can be differentiated with the catalase test?
The morphologically similar Enterococcus (catalase negative) and Staphylococcus (catalase positive) can be differentiated using the catalase test.
What is the function of catylase?
Aparrently, this is a misnomer, and the correct spelling is catalase, an enzyme that breaks down peroxida into water and oxygen.
What enzyme distinguishes staphylococci from streptococci?
Catalase. Staphylococci are catalase positive. Streptococci are catalase negative.
Did the addition of acid increase or decrease the activity of catalase?
Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It requires an optimum pH of 7 to properly function, thus the addition of acid will decrease or deactivate the enzyme.
Why salmonella typhi is catalase positive?
it should test + for catalase but Salmonella isolates are moderate catalase reactors.
Reaction of Bacillus Megaterium in a catalase test?
Most Bacillus species are Catalase positive.
Does Catalase function better at a certain temperature?
Yes, it functions better at cooler temperatures. Hot temperatures cause it to fail to work.
