Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

purpose of this experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in acidic

Cells are the structural and functional units of all living organisms; each specialised to perform dedicated duties throughout their life span. All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells. These two groups are the prokaryotes and the eukaryotes. A Prokaryote cell is the first form of cells for many millions of years until the eukaryote cell evolved from the prokaryote cell‚ which created life. Prokaryote cells are organisms made

BIOL 1364 LABORATORY EXERCISE 3 ________________________________________________________________________ INHERITANCE OF CHARACTERS Objectives of the Laboratory: i) Determination of the genetic control of seed colour‚ ie how many genes control seed colour‚ what sort of intra allelic (dominance relationship) and interallelic interactions (independent assortment vs epistasis) govern the inheritance of seed colour. ii) Understand the scientific process involved in studying character

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Ayaan Nadeem SBI 4UO-A Tuesday‚ February 27‚ 2013 Ms. Balmer Pineapple Jelly Enzyme Lab Discussion After completing the Pineapple Jell-O Enzyme lab‚ the final results were that the canned pineapple formed the jelly while the fresh pineapple did not. Pineapple In order for this to have occurred‚ there has to be a comparison between fresh and canned pineapple in terms of their physical and chemical properties. The physical properties of fresh pineapple are that it is sweet‚ ripe and raw.

(Sudan IV‚ Benedicts’ Solution‚ Iodine‚ Biuret’s) . In order to gain more information for the hypothesis‚ one must know how to test for said macromolecule. Each of the above stated molecules has their own individual solution that will in turn identify

Enzymes are organic catalysts; where a substance speeds up the rate of chemical reactions without changing being changed by the reactions. In lab they tested this by seeing how H2O2 and the catalysts from the banana and liver react to make H2O+O2. Depending on different conditions; like decomposition of H2O2 (surface area)‚ temperature on function‚ reusing the catalase‚ reaction rate of iced liver returned to room temperature‚ and effects of pH on enzyme activity‚ to see how much O2 was released
