What is produced when hydrogen peroxide reacts with catalase enzyme
If the enzyme causes the breakdown of a substrate the reaction is example of
a)anabolism b) parabolism c) catabolism d) complexity
Lemon juice stops the browning of potato by
Lowering the ph b) increasing the ph c( neutralizing the ph
Homework Answers
1. Catalase break hydrogen peroxide into water and oxygen molecules.
2. Catabolism is a series of chemical reactions that breakdown molecules of substrate.
3. Lowering the pH. Lemon juice have ascorbic acid with low pH and oxygen will react with it before it will react with the polyphenol oxidase.
