Catalase is an enzyme that specifically acts on hydrogen peroxide (H2O2) as its substrate. The enzyme's active site is complementary to the structure of H2O2, allowing it to effectively bind and break down the substrate into water and oxygen. This specificity is a key feature of enzymatic reactions, ensuring efficient and selective catalysis.

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 is the basic difference between catalase and peroxidase?

Catalase is a member of the peroxidase family. Catalase generates water and oxygen while peroxidase generates water and an activated donor molecule. Thus, peroxidase could refer to more than one enzyme.


What determines an enzyme's functions and how many functions does one enzyme have?

An enzyme has only one substrate that it works with so it has only one function. This is called a lock and key mechanism. Other things can affect the enzyme such as temperature, pH level and levels of either the substrate or the products. High temperature can denature the enzyme (they are proteins). They can not fit the lock (substrate).

Source of error in catalase lab?

One potential source of error in a catalase lab could be contamination of the catalase enzyme solution, which could lead to inaccurate results. Another source of error could be improper handling or storage of the catalase enzyme, affecting its activity. Additionally, variations in the temperature, pH, or substrate concentration during the experiments could introduce errors in the data collected.


What is the name of an enzyme only acts on one substrate?

Most enzymes are substrate specific because they have a specific shapes active site in which only a specific substrate can fit.


In today's experiment what was one method that you used to denature the catalase?

Allow the temperature to go above that catalysts/enzymes operational temperature. e.g. Yeast works at about 37 oC, however, it denatures above 45 oC.

What is the turnover number for catalase?

The turnover number for catalase is extremely high. One molecule of catalase can easily convert 400 million molecules of hydrogen peroxide to H2O.


Why is the shape of an enzyme important?

The shape of an enzyme is important because enzymes are shape specific. Each enzyme can only react with one kind of substrate, and the enzyme's shape determines which substrate that is. They fit together like a "lock and key". If an enzyme is denatured (or its shape is altered from its active form), then it will not be able to bind to its substrate and the substrate's activation energy will not be lowered, usually resulting in the cessation of whatever reaction the substrate is undergoing.


How many functions does one enyme have?

One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
