Essay On Enzymework

The more acidic a substance is the less oxygen it will produce when going through a chemical reaction. During the Lab “How Do Changes in pH Levels Affect Enzymes Activity”, the researcher conducted an experiment to test the effects that an acidic, neutral, and a base substance will have when combine it with hydrogen peroxide. The data table shows that HCL (acidic substance) barley produced any oxygen at all when it was combining with Hydrogen Peroxide. The pH level for HCL was 2.5; this level indicates that the substance was very acidic. When the H2O and NaOH were tested they produced more bubbles than HCL. NaoH produced a little more bubbles than HCL. The pH that NaoH produced was a 9, which is a base. H2O produced more bubbles than both substances;

These results shown from this experiment led us to conclude that enzymes work best at certain pH rates. For this particular enzyme, pH 7 worked best. When compared to high levels of pH, the lower levels worked better. The wrong level of pH can denature enzymes; therefore finding the right level is essential. The independent variable was the amount of pH, and the dependent being the rate of oxygen. The results are reliable as they are reinforced by the fact that enzymes typically work best at neutral pH

The control group was expected to see a decrease in absorbance because of the starch being digested by amylase. Our experimental group contained everything the control group did, including the Carb Cutter pill. If the Carb Cutter proved to actually work it would show a steady high absorbance, proving that it constantly keeps amylase from digesting the starch.

Hold the IKI spray bottle 25 - 30 cm away from the paper towel, and mist with the IKI solution.

Enzymes are biological catalysts, which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats, carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes, most physiological processes would not take place. Hundreds of different types of enzymes are present in plant and animal cells and each is very specific in its function.

ith the myosin have been activated by the ATP, they will bind the action binding site.

Bacterial amylase is found in different habits for example in human saliva, for this reason is easy

Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department, 2011).

“Enzymes are proteins that have catalytic functions” [1], “that speed up or slow down reactions”[2], “indispensable to maintenance and activity of life”[1]. They are each very specific, and will only work when a particular substrate fits in their active site. An active site is “a region on the surface of an enzyme where the substrate binds, and where the reaction occurs”[2].

Amylase is an enzyme that is located in human saliva. It is solely accountable for breaking down starch as a way to start the breakdown of food and is one of the first steps of digestion. The time at which the enzyme starts the chemical reaction with starch is called the reaction rate. In order to study how amylase works against starch, this experiment consisted of two tests; each testing a different condition of amylase. The first test was to simply study the reaction between saliva and amylase and note the reaction rates. The second test was to see if increasing the pH would decrease the reaction rate or halt it all together. Saliva was collected, diluted, and tested for reactions between starch and amylase. Another sample of saliva was collected, diluted, and had its pH increased and tested for reaction rate. The findings after the experiment was conducted aligned with the original hypothesis. The change in pH did show a significant decrease in the reaction rate.

The RAS protein was examined, and its significance to involved pathways. This review highlights modern studies to solve problems of constitutively activated RAS. Lysine-104 silences RAS signaling pathways when acetylated. Andrographalide and derivatives inhibit RAS from using GEF to exchange GDP for GTP. Mutant K-RAS cells are selectively killed by lanperisone, a muscle relaxant. R-Ras binds to FlNa, causing overall increases in cell migration, but questionable cell adhesion changes. RAS is capable of modulating circadian rhythm functions through over-expression or under-expression. Modern treatments of RAS mutants can be compounded with newly discovered functions of RAS to gain promising research data.

Enzymes in Industry Enzymes are described as chemical a catalyst that is they speed up the rate of reaction. Enzymes have enormous potential in the commercial world. They are cheap to use in industry and they do not need high temperatures to work.

The Industrial Application of Enzymes Enzymes are naturally occurring biological molecules found in all living organisms, plant, animal and microorganisms such as bacteria. All enzymes are proteins and, as with all proteins, are made up of a chain or polymer of amino acids held together by peptide bonds. This chain coils to form a specific three-dimensional globular shape, which, typically, means an enzyme will only work with one specific substrate. The purpose of an enzyme is to lower the activation energy required for biochemical reactions to take place.
