To investigate the effect of surface area on the rate of reaction using the enzyme Catalase, found in potato, and the substrate Hydrogen Peroxide.

INTRODUCTION Enzymes ar biological catalysts that speed up chemical substance answers, without creation apply up or changed. Catalase is a spheric protein pinpoint that is found in all living cells. A globular protein is a protein with its tinges curled up into a ball shape. every last(predicate) enzymes experience an active site. This is where another molecule(s) bunghole bind with the enzyme. This molecule is cognize as the subst account. When the substratum binds with the enzyme, a product is produced. Enzymes atomic number 18 particularised to their subst score, because the shape of their active site will only habilitate the shape of their substrate. It is said that the substrate is complimentary to their substrate. When the substrate binds with the enzyme, it forms an enzyme-substrate complex. The reaction happens immediately after and the substrate is broken expert deal in to either two or more than products causation a catabolic reaction. Or t wo or more substrates argon bonded to make one product causing an anabolic reaction. There are five factors that effect enzyme activity. They are: ·Temperature ·pH ·Inhibitors ·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato, you make more Catalase molecules be exposed to hydrogen peroxide.

This will result in the rate of reaction increasing because it increases the chance of more successful collisions adjoin by the enzyme and the substrate. Catalase is an enzyme found in food such as, potato. It is used to intermit down a poisonous by-product of metabolism ca lled hydrogen peroxide. Hydrogen peroxide i! s a compound that can consume cells therefore; it is essential that our body can infract it up. Catalase breaks down hydrogen peroxide into oxygen and water. Below is the reaction equation for the chemical decomposition reaction of hydrogen peroxide. 2H2O22H20+O2 prophecy To increase the surface...
