Enzymes: Biological Catalysts www.assignmentpoint.com
Catalysts • speed up the rate of the reaction. • lowers the energy input required for a chemical reaction to happen • remains unchanged at the end of the reaction skool www.assignmentpoint.com
Enzymes • Enzymes are Biological catalysts • Enzymes control chemical reactions that take place in the cytoplasm. • http://programs.northlandcollege.edu/biology/Biology1111/animations/enzyme.html • Catalase in an example of an enzyme made by living cells www.assignmentpoint.com
Catalase • The enzyme catalase breaks down the waste substance hydrogen peroxide into water and oxygen. catalase Hydrogen peroxide oxygen +water (enzyme) (substrate) (products) www.assignmentpoint.com
