[Name] [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on

table of results. The graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second

The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize

for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a reaction

Purpose The purpose of this catalase lab is to design simple experiments to demonstrate how various factors affect the rate of enzyme activity. This lab shows how the enzyme decomposes in hydrogen peroxide.

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

THE EFFECT OF CATALASE ON HYDROGEN PEROXIDE The aim of the experiments is to see if increasing the surface area of the enzyme Catalase‚ affects the relative activity of the substrate Hydrogen peroxide. Then to observe and measure the effect the Catalase has on the chemical breakdown of the hydrogen peroxide. My theory is if you keep increasing the surface area of Catalase‚ the more active sites are available to join with the substrate causing an increase in the breakdown of the hydrogen peroxide

Catalase Lab Purpose: To observe the effects of hydrogen peroxide on living tissue and non-living materials‚ showing the presence or absence of catalase as observed by the presences of bubbles. Hypothesis: If we pour H2O2 on certain substances‚ the catalase will break down and bubbles will appear at the surface. Data table: Name | Time | Observation | Raw Potato | 1 min. 30 sec. | Slow reaction‚ barley any bubbles. | Raw Liver | 5 min. 30 sec. | Extremely fast reaction‚ very foamy‚ Big
