Abstract The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius.

The Thirteen Colonies 16th century England was not interested in exploration and colonization‚ but for the most part‚ English colonies in North America were more for bussiness and in search of gold . It did provide extra land for Englands growing population and for those who seeked more religious freedom. Englands colonization in the new world led to the Thirteen Colonies made up of the New England Colonies‚ The Middle Colonies‚ and the Southern Colonies each having seperate religious beliefs‚ laws

Omar Shbeeb Toothpick Enzyme Lab 9/25/13 Introduction Enzymes are used in all metabolic reactions to control the rate of reactions and decrease the amount of energy necessary for the reaction to take place. They are responsible for the thousands of chemical interconversions that sustain life. Enzymes are referred to highly selective catalysts‚ meaning they speed up the rate of metabolic reactions. To react‚ they need to find a perfect match with a substrate. They converge at a place called an

Antigone The main theme for Antigone is that people sometimes have to learn the hard way from their mistakes. This theme is expressed in the final four lines of the play. They read‚ There is no happiness where there is no wisdom; No wisdom but in submission to the gods. Big words are always punished‚ And proud men in old age learn to be wise. These lines are an important part of the play. They symbolize Creon ’s bad decisions‚ his defiance of the gods‚ the punishment

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of Cannabis sativa

Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties
