Catalase Lab Report Introduction Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. Enzymes work by fitting into certain substrates to lower the energy needed for the process to work. This is similar to the lock and key. The key being the substrate and the lock being the enzyme. If the substrate (key) doesn’t fit it won’t work with the enzyme (lock).
Chromosomal mutation modifies the enzymes that it targets and forms a bond that tricks the enzyme to believe that it a good enzyme. But, sometimes the mutation is not successful in bonding because the mutation was not strong enough to bond completely. An example of how a pathogen can mutate is streptococcal pharyngitis. Streptococcal pharyngitis is strep throat. Most of the time you are given some sort of “cillin”, like amoxicillin or penicillin, to treat the virus.
These tags fool the immune system into thinking that the protein is an invader. The immune system, thinking the organism (the individual) is under attack, sends white blood cells to attack, and that triggers an allergic reaction. These reactions can range from mild to severe. Allergic responses include dermatitis, gastrointestinal and respiratory distress, including such life-threatening anaphylactic responses as biphasic anaphylaxis and vasodilation; these require immediate emergency intervention. Individuals with protein allergies commonly avoid contact with the problematic protein.
Changes in pH break the delicate bonds that maintain an enzyme's shape. An enzyme will unravel, or denature, and become useless in a different pH. The FDA should not approve this enzyme to be safe for people. I say this because for the FDA to approve it, Lactex must be able to survive a wide range of pH and temperatures that it will be exposed to within the digestive tract.

j Abstract Enzyme inhibition is important because it helps cure sickness by injecting the correct inhabitant. PTU was experimented to discover what type of inhibitor it is to Catechol Oxidase (Potato Extract) by seeing if there is a color change when the two interact. Results show that PTU was not a competitive inhibitor, saying that it did not bind to the Potato Extract (Catechol Oxidase. Introduction Enzyme inhibition is important in life because many medications contain enzyme inhibitors, some being competitive inhibitors and other noncompetitive. Competitive meaning it would bind to the active site therefore blocking it decreasing enzyme activity, noncompetitive being that it would just simply bind elsewhere and or change the shape of the enzyme causing no feedback.
Because they create movement within the cell, both the cell as a whole and its subcellular components have the ability to move from one place to another (Kleinsmith & Kish, 1988) [pic](W.H.Freeman & company, 2000) Patients who suffer from Parkinson’s disease have a protein called alpha-synuclein in their brain. The toxic effects from this protein damages neurons in Parkinson’s disease. Study shows that these neurons can be kept protected by inhibiting the action of an enzyme called SIRT2. Microtubules help transport objects within cells and it is known that SIRT2 acts on a huge component of microtubule in order to inhibit its action. Research has shown that inhibition of SIRT2 has lead to microtubule-dependent transportation of alpha-synuclein into large quantities.
Basophils are not well understood, but they function in allergic reactions. They release histamine; which causes blood vessels to leak and attracts white blood cells and heparin; which prevents clotting in the infected area so that the white blood cells can reach the bacteria. Monocytes
The Methods Behind Targeted Chemotherapy Emily A. Abstract The use of the drug Cisplatin through the method of isolated infusion is the ideal use of targeted chemotherapy. Cisplatin works by molecularly targeting the guanine base in DNA, but if it were given through a general IV it would bond with all cells with guanine bases and not exclusively the cancerous cells. Therefore when the drug is administered through isolated infusion (a form of targeted delivery) it will only affect the ‘isolated’ cancerous area. This method of chemotherapy is controversial because if the procedure is not properly conducted the Cisplatin will spread and healthy organ systems could be destroyed. Yet the benefits outweigh the risks by far because if the procedure is done correctly all the cancerous cells in that isolated area will be eliminated entirely.
Experiment title: The effect of the enzyme concentration on the rate of reaction. Objective: To determine the effect of different concentration value of the enzyme amylase in starch solution Introduction: All reactions have different reaction rates. However, there are some common factors that will affect the rate of reaction. These factors are temperature, catalyst, and concentration. In this case, the most effective factor is the reactant concentration, where the reactant is the enzyme.
Here are some reasons why we should avoid genetically engineered crops -Allergens Genetic engineer crops could bring new allergens into foods that sensitive individuals would not know how to avoid. Some studies show that soybean genetically engineered to brazil nuts proteins cause reaction to individuals allergic to brazil nuts. -Antibiotic Resistance Most genetic engineer crops carry antibiotic-resistance genes. Eating these foods could reduce the effectiveness of antibiotic to fight disease. The resistance genes could transfer to human causing them to immune to antibiotic.
