Catalysis

In recent studies, cyanide poison is a toxic substance that appears in different variety of crops. According to Ogundele and Caxton- Martins," Cassava is the most widely consumed of these plants and it has been associated with economic condition in certain parts of the World; especially the tropics and sub tropics." These plants are called cyanophoric plants because they contain phytotoxins. Cyanide is very highly reaction to alkali earth metal. They mostly reactive to salt such as potassium,…

By definition an enzyme are biological catalyst that facilitates specific chemical reactions. What this means is that an enzyme is a protein its function is to function as catalyst which lowers the activation energy for the reaction to occur quicker. Enzymes have different ways that it reacts with substrates. One way is that an enzyme reacts with a substrate is by bringing two substrates together correctly or by stressing particular bonds of substrates. By doing on or the other an enzyme can…

The purpose of this experiment is to discover which environmental factors, the independent variables, are most optimal for enzyme functionality and how they affect enzyme functionality. Enzymes help speed up chemical reactions in the body and lower the activation energy to do so. Enzymes can also aid with metabolism and digestion. They can break down larger molecules to smaller molecules that are more easily absorbed by the body. A substrate is the reactant that is acted upon by an enzyme in a…

Enzymes, usually proteins, are biological molecules that increase chemical reactions. Enzymes are important for survival and they help out in several different functions throughout the body, such as assisting metabolism and digestion. Though not all, some enzymes take apart huge molecules into smaller parts which can be much simpler for the body to digest. For each experiment, I came up with a hypothesis before testing/knowing the results. When amylase influenced starch disappearance, I…

Introduction: Enzymes are a type of the macromolecule protein, used in metabolic reactions that occur within the cell of living organisms. The role of enzymes in these reactions is to decrease the amount of energy needed to start the reactions, thus assisting the metabolic process by increasing the speed at which the reaction occurs. In other words, enzymes allow the metabolic process to happen faster than it would naturally, making them catalysts. The structure of an enzyme is important to…

Enzymes are biological catalysts that increase the rate of a reaction by reducing the activation energy required for a reaction. Many enzymes are proteins but not all are; enzymes possess high levels of substrate specificity which they bind to through their active sites. Enzymes display optimal activity at a certain pH level and temperature. Temperature and pH level have drastic effects on enzyme activity; the enzyme will denature if the pH or temperature has changed from its optimal level.…

EXPERIMENT: The effect of an acidic fluid on the activity of an enzyme INTRODUCTION: There are several factors that may influence the activity of an enzyme to include temperature and the pH levels. In order to better understand how the pH level affects the actions of an enzyme, the experiment will introduce different foods with acids and bases through mixture of direct contact. OBJECTIVE: The objective of this experiment is to recognize how the introduction of an acid affects the activities of…

Enzymes are macromolecules that act as a catalyst in order for chemical reactions to occur. Their function is highly dependent on what the structure of the enzyme because they have things called active sites that recognize specific substrates. A substrate is a molecule that fits into the active sites of enzymes so a reaction can occur. For example, sucrose (substrate) fits into sucrase (enzyme) where hydrolysis occurs consequently splitting sucrose into glucose and fructose. However, in our…

Enzymes are proteins serving as catalysts that carry out thousands of chemical reactions that occur in living cells. A catalyst speeds up a chemical reaction by changing the rate of the reaction without being consumed by the reaction. In an enzyme - catalyzed reaction the substance acted upon that is called substrate binds to the active site of the enzyme. An enzyme-substrate complex is formed held by hydrophobic interactions, hydrogen bonds and ionic bonds. The substrate is converted to…

Liquefaction and gasification in supercritical water (SCW) are two processes for transferring substances into liquid and gaseous fuels, which is special for high moisture substances6. Supercritical water, which is serve as the solvent and the reactant in these reactions, mainly decreases mass transition restrictions in ambient condition water; therefore, it helps to accelerate the chemical reactions largely9. However, the vaporization of water along with raw materials is required by traditional…
