proteins which act as effective catalysts for biochemical reactions within an organism. Enzymes are distinct from one another; they attach themselves to specific slots on substrates called active sites to lower the activation energy to start the chemical reaction. This is represented by the lock and key model, where the shape of the enzyme directly corresponds to the substrate to carry out a specific job. An enzyme is able to be used until it becomes denatured, or when the active spot of the enzyme

Enzymes are proteins that are made by living cells. They act as catalysts, speeding up the chemical reaction process, remaining unchanged before and after. They do so by lowering the activation energy, meaning when they are present, less energy is required for the reaction to occur. The enzymes act on a substrate during the process. A substrate is any compound the enzyme bonds with. However, the substrate must match a specific shape for the two to bond properly. This is known as the key and lock

Christian Rodriguez Mrs. Gentry AP Biology September 27, 2015 Lab Abstract Enzymes are proteins produced by living cells. In an enzyme, the substrates bind with the active site of an enzyme, breaking them down into other molecules. Enzymes acts as catalyst which lower the reaction energy and allows it to take place in less time and at lower temperatures. Enzymes can be used in a reaction without actually being used up; therefore, they can be used reversibly. Temperature, salt concentration, substrate

A miniscale diels-alder reaction was performed between the conjugated diene 2,3dimethyl-1,3 butadiene and a substituted alkene such as maleic anhydride in order to produce a substituted cyclohexane. The substituted cyclohexane produced was 4,5-dimethyl-4-cyclohexene-cis-1,2-dicarboxylic acid anhydride. A diels- alder reaction does not have an intermediate state, meaning that bond breaking and bond making occurs at the same time. Heat needs to be applied in order for the reaction to occur and it is

states that the cement and steel pipe are to protect any water supply around. The article states that after the pipe is finished water mixed with sand and chemicals are flowed through the pipe with pressure. The purpose is to restore fractures that are in the reservoir to ensure best outcomes of pumping the natural gas and oils. The chemicals are said to each have a specific purpose such as; protecting metal pipe, fixing mud damage, reducing mud damage, and stopping micro-organisms (Bierstedt, 2015)

Intracellular activity has always been of interest to scientists and non-scientists alike. What causes a cell to work and how exactly does it carry out these actions? Enzymes play a huge part in cellular activity, as was discovered in 1896 (Human Touch of Chemistry). Enzymes were originally found while trying to ferment glucose into alcohol. Scientists couldn't figure out how to carry out this process without living yeast. Eduard Buchner proved that glucose could be turned into alcohol without

world that when Mentos react with Diet Coke, it is a chemical reaction. This statement though, is proven to be false. If you look at the definition of a chemical reaction, it is a “process that involves the rearrangement of the molecular or ionic structure of a substance.” When a Mento is dropped into Diet Coke it is’t changing the molecular structure of the substance, it is just simply changing the phyiscal structure. Instead of a chemical reaction happening, it is what they call “Nucleation

1Troops dug a network of trenches that stretched from the English Channel to the Swiss border. The space between the opposing trenches is “no man’s land” a rough landscape with craters from artillery fire. They used modern rifles and a fire machine gun. 2The Germans used poison gas in the Second Battle of Ypres. The fumes caused vomiting, blindness, and suffocation. The British used the tank into battle they were very slow and cumbersome, mechanically unreliable, and fairly easy to destroy and

1. Part A.2. What is the formula and the color of the gas that is evolved? The name of the brown colored gas is nitrite, and its formula is NO2 (Beran, 2014). 2. Part B.1. When the NaOH solution is added, Cu(OH)2 does not precipitate immediately. What else present in the reaction mixture from Part A reacts with the NaOH before the copper(II) ion? Explain. The other compound present within the reaction mixture that came from Part A is water, H2O, which reacts with the NaOH before the copper(II) ion
