What substrate does catalase work on?
Catalase Hydrogen peroxide -----------------> Water + Oxygen.
What is substrate molecule?
Is a molecule upon which an enzyme acts. e.g. hydrogen peroxide is the substrate for the enzyme catalase
What is catalase's substrate in this reaction.2h202 and 2h20 plus 02?
h2o2
What does catalase do to hydrogen peroxide?
Because the shape of the active site on catalase only permits it to break down hydrogen peroxide. This is the case for many enzymes such as catalase, although some enzymes can break down more than one substrate.
What product of catalase reaction causes bubbling?
Oxygen is the product of the catalase reaction causes bubbling. pH is varied when testing the effect of pH on enzyme activity.
Factors effecting catalase rate of reaction?
Temperature, pH, Substrate concentration, Enzyme concentration, Inhibitor concentration (ex. ammonia)
Does slow muscle fibers or fast muscle fibers have a higher catalase concentration?
Fast muscle fibers have the greater metabolic activity and have the higher concentration of catalase enzyme.
Hydrogen is a substrate of the enzyme catalase?
Peroxide
What substrate does catalase work on?

Would catalase act on chemicals other than hydrogen peroxide?
Catalase is an enzyme and enzymes work best with a specific substrate. The enzyme can work with any substrate just not as efficient .
What is the substrate of catalase?
A substrate is a substance in which an enzyme reacts. The substrate for catalase would be hydrogen peroxide otherwise known as H2O2.
What is catalase's substrate in this reaction.2h202 and 2h20 plus 02?
h2o2
What concentration of catalase will produce the fastest reaction rate?
o%
The effect of substrate concentration on the rate of reaction of h202 and catalase?
As the substrate concentration increases, so will the enzyme activity and hence there will be a quick reaction. however, only up to a certain point ( where, if you drew a graph of the reaction, the line will level off ) as all the active sites in the enzyme are occupied and the reaction cannot go any faster. Here more enzymes will be needed to speed up the reaction.
Why when adding catalase to sucrose not makes it bubble?
Catalase is an enzyme that is substrate-specific, meaning that it has a particular reaction that it will catalyze (to speed up a reaction). Hydrogen peroxide (H2O2) is the specific substrate reactant with which catalase will react (in a degradation reaction). This is the degradation (breaking down of) reaction. 2H2O2 yields 2H2O+O2 O2 is oxygen which is indicated by the rising of bubbles upon reaction between the hydrogen peroxide and the catalase. Sucrose is not the specific substrate assigned to the catalase enzyme, therefore they will not react together in a degradation reaction, hence the lack of oxygen release (lack of bubbles). I hope this was helpful to you. God bless and Jesus loves you.
Why the streptococcus species that are catalase negative are capable of growth in the presence of oxygen?
Streptococci are facultative anaerobes. They have the superoxide distumate to stimulate O2 which breaks down superoxide. This allows them to tolerate O2 in the absence of catalase activity.
