INVESTIGATION INTO THE 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

Whether or not these innate principles exist‚ holds for many philosophers many important

“Any Human to Another” Countee Cullen was an African American writer during the Harlem Renaissance. His poem “Any Human to Another” calls on whites and Americans in general to put aside their racial differences and come together in harmony. Cullen’s reflective and didactic tone is established through numerous rhetorical dev ices. The first thing one notices when reading the poem is the constantly changing rhyme scheme. Cullen uses a changing meter to emphasize each stanza‚ making them stand

the biosphere is air without which no life can survive (except some lower forms of Bacteria). Without air of good quality there cannot be a healthy life. Yet clean air is a rare commodity today. Air pollution is as old as industrialisation. Discharges from industrial premises to the atmosphere are often more or less continuous during working hours. Polluted air contains solid and liquid particles such as dust carbon‚ hydrocarbons etc. It may also contain gases which are poisonous or abnoxious in

IS THERE ANY DISSIMILARITY IN THE COLORS? There is NOT any kind of dissimilarity in the colors - the colors are totally for the superficial purposes. The glue is of the same potency‚ and it doesn’t make any difference‚ whichever color you make use of while applying. In the instructions‚ we make use of more colors‚ to make it easy for the audience to find when over one strip of tape is used. SHOULD I WEAR IT PRIOR TO EXERCISE?

GMOs are genetically modified organisms that are usually put in crops to make them bigger‚ tastier‚ or healthier. Though this sounds like a great idea there are extreme drawbacks. For instance GMOs are already increasing herbicide use in the U.S. by 26 percent since 1998 when the leaders of GMOs said that they would decrease herbicide use. This also means that more weeds are becoming resistant to herbicides and so GMOs are creating superweeds that are even harder to kill. With the constant spraying

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

responsible for the energy that we‚ and all other organisms‚ need to survive. It is produced primarily in the processes of aerobic and anaerobic respiration by oxidative and substrate phosphorylation. 4 molecules of ATP are produced from 4 ADP and 4 inorganic phosphates in glycolysis in the cytoplasm of every cell‚ by the oxidation of a triose phosphate into two molecules of pyruvate. In anaerobic respiration these are the only 4 ATP molecules produced per molecule of glucose as there is no oxygen

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded
