of synthesis: 1- In pancreas: Synthesis of taurine in the mammalian pancreas occurs through the cysteine sulfinic acid pathway. First‚ in this pathway is oxidation of cysteine sulfahydryl group to sulfonic acid‚ this oxidation is catalyzed by the enzyme cysteine dioxygenase. In turn‚ cysteine sulfonic acid is decarboxylated to hypotaurine by sulfonoalanine decarboxylase. It is not well known whether hypotaurine is then enzymatically or spontaneously oxidized to taurine. 2- in CNS: Biosynthesis of

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand‚ the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B‚ A+C‚ and B+C) Each of these

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease.

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

results. This is due to the enzymes being most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were functioning at a significantly reduced rate at the 24ᵒC temperature and was completely inactive at the 0ᵒC temperature. Whereas when we compare to the higher temperatures (60ᵒC) the enzymes should have functioned

What are Enzymes? Enzymes are proteins that quicken chemical reaction in our body. They are found in our digestive system‚ in the stomach mostly. They are there to speed up the process of breaking down food into molecules that provide nutrients to the body. Enzymes are made up of amino acids. The Digestive System: Many people believe that when you eat a meal it drops into a pool of stomach acid‚ and then it is broken down as it goes into the small intestine to have nutrients taken out‚ and then

Scientific Writing and Standard Components of a Lab Report INTRODUCTION Writing is a powerful tool. Effective communication is necessary to succeed in any field. As a professional‚ you must communicate with both your colleagues‚ and the community at large. Writing is the means of showing the value of your work. The specific style of writing in science is based on the unique audience of readers. In addition‚ writing allows one to organize one’s thoughts and clarify ideas‚ and it fosters abstract

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L
