Enzymes including Catalase lab Flashcards
How do enzymes relate to activation energy?
They reduce the amount of energy needed to get a chemical reaction started
What is an enyme 5 things
special proteins that speed up biochemical reactions
not used or changed in reaction but can denatured
Substrate: Input
Product: Output
2 H2O2 (ALONG WITH CATALASE)-O2 +H20sUBSTRATE IS HYDROGEN PEROXIDE. Catalase helps decomposition of hydrogen peroxide Also changing the active site makes the enzyme non functional
What is the opium temperature range for catalase
37 degrees celsius, higher temperatures, enzyme would denature
lower ones, the enzymes did not activate much and get the reaction going.
What is the opium pH range for catalase?
The opium pH range was 8.
what is an enzyme
Enzymes are special, globular proteins in tertiary structure that increase the rate of biochemical reactions. They remain unchanged after causing a reaction. However, they may denature, or damaged in certain conditions. All enzymes have an active site, the part of the enzyme where the reactions take place. When the active site shape is altered via denaturation, that enzyme can no longer carry out its specific reaction, because the active site can no longer fit perfectly with the molecule the enzyme is specified for. The enzyme being tested in this lab is catalase, a specific enzyme in the human body that increases the rate of the decomposition of hydrogen peroxide. The enzyme will produce water and O2.
Most biological enzymes denature at temperatures over 40 degrees Celsius. Certain pH levels in which the enzymes are can also contribute to the denaturing of enzymes.
