Angiotensin-converting enzyme

Introduction/Hypothesis Enzymes are catalysts used to speed up reactions and reduce activation energy. These enzymes are important to many bodily functions. Catalase is one of the enzymes essential to cellular health within the body. It is responsible for the breakdown of hydrogen peroxide which, if it builds up, is extremely toxic to cells. One question that scientists have asked and a question that we explore in this lab is what are the optimal conditions for this reaction to occur? This lab…

i. Enzymes are macromolecules that increase chemical reactions without being consumed in the reaction. They do this by lowering the activation energy (the amount of energy that reactants need to absorb in order for a chemical reaction to take place). Every enzyme has a substrate with a unique shape and structure for it to bind to. Denaturation of proteins (when a protein unravels and becomes inactive), and change in the shape of the enzyme or substrate all influence the activity and…

each time mark, which led to varied enzymatic activity and inconclusive or atypical results. Slight water residue was observed in the test tubes prior to use in the experiment, and may have contributed to the overall lack of enzyme activity (i.e. water may have diluted the enzymes). The iodine solution added to the spot plates just before the amylase-starch solution was added may have also contributed to the inconclusive results as it may have oxidized too quickly and the bond it should have…

Rate of Reaction for Enzyme Peroxidase When analyzing living organisms, it is merely impossible to overlook the role that metabolism plays. Metabolism, is a series of chemical reactions that occur in a living organisms cells. When referring to metabolism, one must also note that metabolism contains two distinct metabolic pathways, catabolic and anabolic. Catabolic pathways involve the process of breaking down molecules in order to obtain the energy needed by living organisms. Meanwhile,…

catalyzed by enzymes. Without enzymes, most reactions necessary for the maintenance of life would occur so slow that they would not occur at all under the regular temperature and pressure conditions (Cooper). Enzymes act as catalysts that accelerate the rates of reactions by lowering the energy of activation. In an enzymatic reaction, the substrate (which is the reactant that an enzyme acts on) binds to the active site (which is the region on the enzyme where the substrate binds to) of the…

Ultrasound and meat quality The quality of meat is based on aroma, taste, appearance, texture and juiciness. Texture is the most important factor in determining the quality of meat as per consumer behavior. There are several factors that affect texture such as the tenderness of the meat, juiciness and the degree of maturation. Tenderness The quality of meat as a result of using Traditional tenderising methods is poor. This includes mechanical, enzymatic and chemical methods…

During the phase and process of the bacterial unknown project, vast amounts of test were performed in order to determine an unknown species of bacteria. Within the many procedures of identifying the unknown bacteria, I was first given a tube with the unknown bacteria, from which later on I started subcultures by streaking bacteria from the original tube onto a tryptic soy agar (TSA) slant. Throughout the process of identifying the unknown, new subcultures were produced in order to use the newest…

Enzymes are catalysts to help facilitate chemical reactions (RSC 2004). They do not cause the reaction to occur, but they speed up the rate of reaction (RSC 2004). Each enzyme is a specific protein, meaning they work for the purpose of a particular reaction or substance (EUFIC 2016). This can help explain why they are essential in the role of digestion. The particular enzyme that we looked at in this experiment was salivary amylase. Salivary amylase is an enzyme that helps with the breakdown of…

basics of enzymes and how they work. We were able to perform a quantitative assay of the activity of an enzyme in a tissue extract using a spectrophotometer. Also, we had to organize the data that was provided into tables and graphs so we could have the ability to test a few hypotheses. For example, we tested the whether the rate of the reaction was influenced by enzyme concentration, whether the activity of the enzyme was influenced by temperature and also too see if the activity of the enzyme…

What is the necessity of blood glucose level chart? Description: Blood glucose level chart is of greater important especially to those patients who are diabetic in nature. The chart should be prepared in a proper manner so that you can get the highest benefits. Do you wish to make effective diabetes management? Well, in this case you just need to follow a proper blood glucose level chart. This chart cannot be prepared by self-efforts rather you have to take the help of any expert doctor who is…
