Chemical equilibrium

While researching the greatest chemists that have ever lived, I could not help but notice one who was missing from the list. Boyle, Mendeleev, and Lavoisier were on everyone’s list; and rightfully so, but I believe that people overlook the outstanding work of Henry Louis Le Chatelier. Le Chatelier studied chemistry extensively in school and made great discoveries as a teacher of the science at colleges in France. He is most known for the principle named after him: Le Chatelier’s Principle, which

as a catalyst, which is anything that helps to speed up, or catalyze, the chemical reaction (Bolster&Moss, n.d.). To speed up a chemical reaction, enzymes lower the activation energy, which is the initial energy required for a reaction to occur by applying heat. However, enzymes are very substrate-specific, only acting on specific reactants, which are the substrates, and consequently, enzymes are selective in the chemical reactions that they catalyze. Since an enzyme is a protein, each enzyme

does changing enzyme concentration or temperature affect the reaction time of enzyme activity? Background and Introduction: Enzymes are proteins that process substrates, which is the chemical molecule that enzymes work on to make products. Enzyme purpose is to increase the rate of activity and speed up chemical reaction in a form of biological catalysts. The enzymes specialize in lowering the activation energy to start the process. Enzymes are very specific in their process, each substrate is designed

Although the original function of HbHNL is to produce HCN from acetone cyanohydrins for plant defense purpose, its reversible reaction to produce enantiopure cyanohydrins makes it an industrial relevant enzyme (Fig. 1.6a). Besides acetone, it is also able to take a bigger substrate such as benzaldehyde and turn it into mandelonitrile with optical purity up to 99%.15 HbHNL is known to turn different aliphatic or aromatic aldehydes and methyl ketones into different cyanohydrins.15 Cyanohydrins are

the Speed of Reaction Abstract This experiment tested the effects of pH on enzyme activity and how the concentration of enzyme affects the rate of reaction. Enzymes, biological catalysts, are sensitive to changes that can affect the rate of the chemical reaction. The specific enzyme used in this lab was Catecholase, an enzyme found in the cells of many fruits and vegetables. In the first exercise, the greatest amount of product was produced at a pH of 6, which was the most effective pH on the enzyme

effect of pH on catechol oxidase: pH along with temperature and concentration is a limiting factor of enzyme activity. Enzymes, which are proteins, have a distinct pH range in which they work most effectively. Beyond or below this specific pH, enzyme activity begins to diminish and eventually the enzyme is rendered useless. The optimum pH of an enzyme is the pH at which it is most effective and causes the fastest rate of reaction(source). This decrease in enzyme activity beyond the optimum pH is

An enzyme is macromolecular catalysts that is produced by a living organism. Each enzyme only speeds up a specific reaction which means that every enzyme speeds up what goes on inside the cell in a certain area. Enzymes can sometimes break down bigger molecules into smaller ones so the body can absorb them. When an enzyme doesn't break apart it binds two molecules into one molecule. The molecules that enzymes help out are called substrates. Substrates bind together to make a region called the active

Enzymes are biological molecules, mostly proteins, that speed up the rate of the chemical reactions that take place in the cells (Joseph Castro, 2014). They are proteins that act as catalysts within living cells. However, catalysts is used to increase the rate at which chemical reactions occur without being altered. A chemical reaction is a process that converts one or more substances, called substrates, to another type of substance, which is the product. With the catalyst, the enzyme can perform

Cellular Respiration, Digestion, etc. Within these reactions, molecules change their identity and transform into new molecules. In the middle of these molecular transformations are enzymes (sites.com). Mostly made of protein, enzymes help catalyze chemical reactions quicker by lowering the cell’s activation energy to complete a reaction, all while keeping its shape. A molecule or substrate will bind with an enzyme on its active site and reactants

inhibitor existence are made considering the kinetics of a specific enzyme? While examining the results these variables significant to the enzyme kinetics will provide a understanding of the general enzyme activity. Observing the end products of each chemical reaction that included an enzyme produced a velocity of that certain enzyme involved, which is measured. These results in this experiment will show temperature change, substrate concentration change, enzyme concentration change, and existence of
