Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a little activity would take

wildlife conservation high on the agenda. US Interior Secretary Sally Jewell said about 20‚000 elephants were slaughtered in Africa last year‚ while about three rhinos were killed every day in South Africa alone. “This hugely profitable illicit activity generates billions of dollars in revenue every year‚ fuelling growth in international criminal syndicates and reversing decades of hard-won conservation gains across the continent‚” Jewell said.

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

enough acid to have a pH of 4.6 or lower. Acidic foods can be processed safely in a boiling water canner‚ usually without added acid (lemon juice‚ vinegar or citric acid). This is necessary to control botulinum bacteria. Acidity may be natural‚ as in most fruits‚ or added‚ as in pickled food. Low-acid canned foods are not acidic enough to prevent the growth of these bacteria. Acid foods contain enough acid to block their growth‚ or destroy them more rapidly when heated. The term "pH" is a measure of acidity;

Enzymes are catalysts that increase the rate of chemical reactions organisms‚ allowing cells to break or build things instantly. The structure of an enzyme is essential to its function. Enzymes are proteins‚ made up of 100-1000 amino acids bonded together in chains. These chains are folded/coiled into a unique 3-D structure that allows them to bind to a reactant‚ called a substrate at an active site. Enzymes are flexible‚ and therefore can change it’s shape to better accommodate its substrate; this
