  • Cofactor And Enzyme Reaction

    Introduction What are enzymes and how do they affect reactions? Enzymes force reactions, in cells, to maintain a speed necessary for life. Enzymes can also be considered catalysts because they require the reactions to arise faster without themselves changing. For this experiment, the substrate in the enzymatic reaction was sucrase, and it will be causing sucrose to change resulting in the following equation: Sucrose → Glucose + Fructose Where the arrow is in the equation indicates the enzyme, sucrase, used to speed up the reaction. In the experiment conducted we were looking for the effect of a cofactor that could have impacted enzyme activity. A cofactor is required for enzymes to function properly. In order to catch sight of the reaction occurring, we must use catechol, because it is colorless and then observe it being catalyzed changing it to benzoquinone. Benzoquinone is reddish-brown so the reaction of catechol to benzoquinone can be easily seen, however for it to occur you must have catacholase. Catacholase is the catalyst for the conversion of catechol to benzoquinone. The equation for catechol to benzoquinone is: Catechol + O2 → Benzoquinone + H20 Where the arrow is, for this experiment, is catacholase. However, this reaction occurs countless times throughout life without that enzyme actually being present. For example, when an apple turns brown after being bitten, is an example of this reaction. The variable that was being tested in this experiment was the…

  • Essay On Grass Tetany

    can result in hypomagnesemia. Treatment/Prevention Grass tetany affects all ruminants who are grazing in areas that have been deemed dangerous. Schonewille (2013) suggested that a dangerous pasture is one that has limited floral growth and exhibits the characteristics that are associated with hypomagnesemic conditions. As such, grass tetany can be easily prevented by carefully analyzing the pastures where cattle are grazing to determine whether or not the flora is healthy and possesses a…

  • Recrystallisation Lab Report

    excitation energy, and thus a decrease in ligand field strength due to the mode of ONO. It was also reflected in table 1 that the green complex "[Ni" ("O,O '-ONO" )_"2" ("N,N,N ',N '-tetrameen" )"]" exhibited smaller ν_as and ν_s than free nitrite ions. Also, in comparison to the unidentate nitrito blue complex, the ν_as and ν_s was shifted to lower and higher frequencies respectively. This signified a chelating complex with bidentate nitrito groups, where the chelation maintained the…

  • An Essay On Thalassemia In Children

    include blood transfusions, iron chelation therapy, blood and marrow stem cell transplants, and folic acid supplements. The worst type of thalassemia that a patient can live with is beta thalassemia major. Alpha thalassemia major, also known as hydrop fetalis, will kill the patient before they can live long, so complications with hydrop fetalis do not persist for long. However, patients with beta thalassemia major suffer with the disease for life. Patients normally show symptoms of beta…

  • Lead Exposure Effects

    release of the neurotransmitter called glutamate, which is important in many functions that deal with learning and cognitive abilities (2). Lead has also been shown to cause programmed brain cell death in many animal studies (6). Another way lead is toxic is by having a negative effect on the synthesis of heme, a cofactor substance required for hemoglobin and cellular respiration (2). This negative effect results in fatigue and anemia in beings exposed to lead. When it comes to treatment and/or…

  • Euromd Research Papers

    at the expense of the patient’s immune system, so EuroMed Foundation utilizes an integrative treatment philosophy with an emphasis on maintaining the patient’s immune strength, while using very low-dose chemotherapy in the form of Insulin Potentiation Therapy (IPT), which specifically targets cancer cells. Three primary treatment areas are emphasized at EuroMed Foundation: • The patient’s immune function is paramount, so treatments are designed as immune support, including IV glutathione, alpha…

  • Atherosclerosis Case Study

    already experienced a cardiac event or have documented atherosclerosis, treatments include: Angiotensin-converting enzyme (ACE) inhibitors to reduce blood pressure, antiplatelet agents such as heparin and clopidogrel, HMG-CoA reductase inhibitors or statins to lower cholesterol such as Lipitor and Crestor, fibric acid derivatives such as fenofibrate, bile acid sequestrants, Vitamin E, and Omega-3 fatty acids. Lipid lowering treatments help to stabilize vulnerable plaques by inhibiting the…

  • Common Signs And Symptoms And Risk Factors For Anemia

    large amounts of iron are often harmful, iron supplements be solely be taken by the doctor’s prescription. Pernicious anemia caused by low levels of vitamin B-12 is usually treated by B-12 supplements. Folic acid is required for creating and maintaining new cells. Some food sources made in folic acid are eggs, fruit juices, bread, and pasta. Vitamin C helps in absorption of iron within the body. Good sources of Vitamin C are vegetables and fruits. Some of the medication doctors prescribe to…

  • Platelet Poor Clasma Case Study

    Case study one 1. Principle of APTT: Platelet poor plasma (PPP) is incubated at 37 degrees Celsius then phospholipid (cephalin) and a contact activator (e.g.: Kaolin, ellagic acid) are added followed by calcium (all pre-warmed to 37 degrees Celsius). Addition of calcium initiates clotting and timing begins. The APTT measures the time required to regenerate thrombin and fibrin polymers via the intrinsic and common pathways. Reagents:  Platelet poor plasma (PPP)  Surface activator: example;…
