Enzymes are biological molecules macromolecules that catalyze chemical reactions. Enzymes are usually proteins; however, it has been discovered that some enzymes are RNA molecules. The molecules at the beginning of the process to which enzymes act upon are called substrates, which are converted to the products by the actions of the enzyme. Almost all metabolic processes require enzymes to catalyze reactions to a rate that is fast enough to sustain life. Enzymes increase the rate of the reaction…

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present…

Molecules are a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central…

6.3 Results and Discussion 6.3.1 The influence of high pressure on the kinetics of α-chymotrypsin The choice was determined by the fact that the catalytic mechanism as well as pressure stability of this enzyme is well established. α-chymotrypsin-catalyzed hydrolysis proceed according to the Michaelis–Menten mechanism. The initial process involves creation of a stable enzyme substrate complex ES, which is related to KM, afterwards activation of the ES^≠ and subsequent reaction steps occur,…

My Element is the Most Important Element (Argon) •Atomic mass 39.948 •Atomic Number -18 •Gas at 298 K •Density-0.0017837 grams per cubic centimeter •Third Noble gas •Chemical Symbol-Ar •It is also obtained from the air as a byproduct of the production of oxygen and nitrogen •It is the third most atmospheric gas •Argon is colorless and odorless •Argon is non reactive and has no effect on living organisms •Makes up 1% of the air around •Argon is found in the earth’s crust…

Nerve agents are chemicals which are used for warfare purposes in attempts to kill mass amounts of soldiers. This form of warfare has become so heartless, that even Adolf Hitler himself refrained from using them against the Allied Forces during the Second World War. Nerve agents are all based around phosphorus. In the 1930s, the very first nerve agent of the “G Series” was created. This is known as the “G-Series” due to the fact they were all originated in Germany. There are four types of nerve…

Chandross of Bell Labs’ oxalyl chloride and hydrogen peroxide glow stick was patented in 1960’s. Chemiluminescence is a luminescence resulting from a chemical reaction which is how glow sticks work. A glow sticks has a glass vial, a small glass or plastic bottle for holding medicines, and you break the glass by bending the stick. This then causes the chemicals in the stick to mix and a reaction takes place. This experiment will test the length of time glow sticks radiate in different…

one’s in flint. The reason many people are not lead poisoned despite the fact that most of the pipe use to travel the water are made of lead. The reason lies in the complex chemical reactions that goes on between the pipes and the water that flow through it. “ inside the pipes, as the water goes through it, it react. The chemical reactions take place with the plumbing materials and this build up some kind of a protective coating, what they called a scale.this protective scale is very crucial,…

describe many things. However, all three combined only seem to describe Birthstones. Birthstones are amazing objects that affect our economy in many ways. More importantly, birthstones have a deep connection to chemistry and science. Due to their chemical properties, birthstones can also be used for medicinal purposes and healing techniques that have helped humans throughout time. Overall, birthstones contain many disciplines and the concept is one of the most interesting created during the…

The Earth is covered by about 70% of water and naturally, water is the only material that exists in three different states (solid, liquid and gas). This highlights that water is an important component as a chemical substance and this is due to its unique properties. Structure of water is one of the main features of water that allows it to carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has…
