An enzyme is a protein that speeds up the rates of chemical reactions. They recognize, bind, and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction.

A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance with its molecular structure.

A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance. When a chemical reaction happens the atoms in any kind of matter can stick to some other molecular structure.

Metabolism is the chemical processes that occur within a living organism in order to maintain life. Metabolism is when a cell maintains a temperature to stay alive and let its cell’s to carry on with their daily tasks.

Hydrogen peroxide is a substance that contains two hydrogen atoms and two oxygen atoms. Hydrogen peroxide is a weak acid and does not react formally with base substances.
Catalase is found in many foods like beef liver, carrots, wheat sprouts, and potatoes, and more.
Catalase is released when a protein is coming into the stomach a protein catalase goes and transforms the protein into food for human’s internal cells.
Bubbles in an experiment where a raw potato is put into hydrogen peroxide means that the potato catalase was reacting with the molecules of the hydrogen peroxide. Bubbles (a gas) are the product of the reaction in the above listed experiment.

Enzymes when heated, cooked, or put into extreme conditions get denatured.
The purpose of the laboratorial experiment is to determine factors that influence how well (quickly) enzymes function.
