Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Countries like China‚ Japan‚ Singapore‚ Australia & Pakistan have joined the project‚ Strategies to Prevent Suicide (STOPS)‚ in order to lessen their increasing number of suicide. However‚ in trying to prevent the increase in number of suicide deaths and attempts‚ one must know what the leading causes of it are. Suicide rates change over time‚ and the factors influencing them remain poorly understood. Economic

Part I – Relation between BI rate and banks interest rate A. BI rate We take the BI rate‚ as the variable being estimated‚ from the period of 2006 until 2012. We then take the average rate in each year‚ rather than taking the rate in each month. As a note to the year 2012‚ we take the average rate that ranges only from January until August. Figure 1.

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

Oil and gasoline prices had been a problem since individual vehicles had actually entered the market. After the Katrina United States current economic growth is not even sustainable under the recent oil price surge. Even though the Department of Energy does not feel that oil prices are high enough to cause a recession‚ the consequence of high energy costs cannot go unaddressed. Government has to start looking and actually spending money on solutions to this consumption problem immediately. This
