Angiotensin-converting enzyme

Reviewing my data table and graph results it is clear to see that as the substrate concentration increases so does the rate of reaction. The catalysing of enzymes involves molecular movement of the substrate and enzymes in an aqueous solution. Therefore the substrate and enzymes are moving randomly within the solution (Brownian motion). By increasing the concentration of the substrate particles the rate of reaction is increased as the substrate is much more likely to find an active site. This…

Before beginning he experiment the physical appearance of all the chemicals being used needs to be written down. To begin the experiment 3 test tubes must be acquired; a boiling tube, large test tube and a small test tube. The large test tube must be completely dried with a paper towel and labeled R for Reactants. After that is done a piece of weighing paper should be placed on a balance and tared. After make sure the balance is correctly tared, a spatula must be used to collect 2 grams of…

Triiodothyronine, with a chemical name of 3,3',5-Triiodothyronine (T3), is one of four thyroid hormones that exhibit biological activity, and contains 3 iodines and 2 tyrosine’s, as seen in Fig. 1. 20 % of T3 is formed from the amino acid tyrosine within specific follicle cells of the thyroid gland by the oxidative condensation of its biological precursors, monoiodotyrosine and diiodotyrosine, and is then subsequently secreted into the bloodstream. The remaining 80% is produced from the…

The article, Aging Aquifers by Valerie King states the importance of dating groundwater. King begins by stating dating aquifers can predict 50 years down the road. It is important to date groundwater to know the accessibility of water for future use. Dennehy states, “In very old groundwater, when you’re extracting water you should realize that water took a long time to get into that location, so it would take a long time to replace that water” (King 11). Dating aquifers is done by testing the…

The exocrine function is the releasing of enzymes by the pancreas into the duodenum, the first 25cm of the small intestine, joining with the bile that is produced in the liver and stored in the gallbladder. The pancreas produces pancreatic juice and sodium bicarbonate, NaHCO3. Pancreatic juice contains three hydrolytic enzymes: Pancreatic amylase, which breaks down carbohydrates into disaccharides, Trypsin, which breaks down proteins…

interacts with the hydrogen peroxide. The hydrogen peroxide is altered when two substances are combined. The oxygen gas, as a product, comes from the hydrogen peroxide. Enzymes are big proteins that speed up the rate of a chemical reaction by moving as a catalyst. A catalyst provides the environment for the reaction to occur. Catalase is an enzyme in the liver that breaks down dangerous hydrogen peroxide into water and oxygen. When this reaction takes place, oxygen gas bubbles breakout and…

called glucagon. The glucagon is released into the bloodstream and sent to the liver. The glucagon binds to its receptor/target cells, it also changes the shape of the receptor and activates enzyme activity inside the cell. Chemical reactions as a result of this process lead to the production of the same enzyme that is used to convert glucose to glycogen, phosphorylase. The phosphorylase catalyses the reaction of glycogen back to glucose, this process is called Glycogenesis. As the levels of…

The Effects of Competitive Inhibitors on Catechol Oxidase Enzyme Activity. Jaley Willingham, 2015, Functional Biology, Texas State University, San Marcos, 78666. Abstract Competitive inhibitors may have an effect on enzyme activity. We investigated the effects that parahydroxybenzoic acid has on the enzyme activity of catechol oxidase. For this experiment, different levels of parahydroxybenzoic acid concentration were added to catechol oxidase. Each level of concentration was then tested for…

When analyzing the given graph showing the relationship between anaerobic respiration and temperature, it can be seen that at -20°C the amount of fermentation during anaerobic respiration is zero, as the temperature increases the amount of fermentation increases, until 35°C when fermentation is at 100%. Interestingly, as the temperature increases further, fermentation decreases until at 60°C it ceases once more. At Earth’s beginning it is thought that the earth was covered with active volcanoes…

The structure of an enzyme is important because if the structure of the protein is denatured, the protein can not function properly either. Being denatured can be caused by many things but changing the pH or temperature are the main ways to make a protein not to function properly. Any little change in the sequence from protein folding can cause dramatic consequences that might lead to disease or sickness. Cystic Fibrosis is a common disease that affects the whole body, the main and most…
