Aim: -

This is an experiment to show how different concentration of celery tissue enzyme, catalase breakdown the bonds of hydrogen peroxide, substrate, to produce oxygen given out at different rate of reactions.

Planning

Background research:-

Catalyst:

Catalyst is a substance that speeds up the chemical reactions, without it self being consumed by the process. Any such process is called catalysis. In industries, catalysts are used to speed up many chemical reactions that otherwise will take place too slowly to be practical.

Enzymes:

Enzymes are proteins. Like other proteins, enzymes consist of long chains of amino acids held together by peptide bonds. Enzymes take part in the breakdown of food materials into simpler compounds. They are also called biological catalyst. This means that by their mere presence, and without being consumed in the process, enzymes can speed up chemical processes that would otherwise run very slowly, if at all. Enzymes are normally named after the reactions they catalyse because their molecular structure is very complex and in many cases unknown. For example, super oxide dismutase is the enzyme responsible for the destruction of the super oxide ion in living organisms.

Enzymes are
