Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. While Prokaryotes contain just one copy of each gene‚ eukaryotic cells have two. For such reason‚ prokaryotes are known as haploid and eukaryotic as diploid. 2. While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type of cell has different

The Affects of pH on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy‚ speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing

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

Schools ban students from using cell phones at school and at all school functions? By Olivia Acuña ENG 111G27 9/11/2011 Cell phones have created a new era of communication between students around the world. Some students believe cell phones are helpful to communicate with their friends and family. Others disagree and believe that cell phones are being used in an inappropriate manner‚ during and after school activities. I strongly believe that cell phones should be banned during school

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

What are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase

Cells do everything from providing structure and stability to providing energy and a means of reproduction for an organism. There are many professions that have jobs like the organelles in a cell. One example is a Prison. A prison is a clear representation of a cell because all the organelles have a function that is tantamount to a prison. Also it is logical because each function have a function that relates to the jobs found in a prison. The Nucleus in a cell controls everything in the cell

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
