Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism, then inhibition may lead to death of the cell or organism. It is now possible to …
Another source of error is that possibly the ice and salt did not get to a low enough temperature, but again I would think this would alter the results giving a higher temperature instead of a lower one. Something that would give too low a …
Niels Bohr is a big person in the history of chemistry. If it wasn’t for him we would not have known as much as we do now about the atom. He came to a conclusion of so many unanswered questions people were left after the …
Nanoscience includes the survey and creative activity of stuffs, devices, and systems by pull stringsing single atoms and molecules. It describes research where the characteristic dimension of 1 or more planes is less than 100 nanometres i.e. , 0.1 micrometers. As we know that all …
Since the beginning of civilization, man has always tried to resource his surrounding for his own benefits and needs. In the early times, man sufficed his need for energy by using wood in terms of fire for cooking and other purposes. (more…)

The primary purpose of this research paper is to find out whether the endoplasmic reticulum in the eggs of animals undergoes any structural or morphological changes during fertilization. The experiment studies this phenomenon by microinjecting a dye in unfertilized egg and then visualized using a …
Oil Conservation Fortnight (OCF) – 4th – 19th January Petroleum or crude oil is a non-renewable energy source that means it is present in the limited amount. If the use of oil will continue with the careless nature it is going to exhaust definitely at …
The Determination of a Chemical Formula 1 Second, you will conduct a chemical reaction with the dried sample, which will produce elemental copper. By measuring the mass of copper that forms, you will have the necessary information to determine the moles of copper and chlorine …
In terms of market potential, Japan is a significant market for prestige cosmetics next to the United States. This market is clearly critical for P&G’s strategic expansion plans in Asia given that the company’s Max Factor brand has barely cracked the $10 billion Japanese beauty …
DNA is a nucleic acid that is basis of genetic information. It is like a set of instructions for our bodies and genetic codes. DNA has many different components that make it up such as hydrogen, oxygen, nitrogen, and phospurous. The structure has two long …
The purpose of this experiment was to observe the process in which cells must partake in a respiration process called anaerobic fermentation and as the name suggests, oxygen is not required. This particular procedure, which Is catabolic meaning, it breaks down energy, can be present …
A renewable energy source plays a vital role in the future existing applications such as solar energy, geothermal heat. In the development of the energy in the heat transferring applications, the thermal conductivity plays a vital role. For the development of the energy efficient usages, …
Sustainable development requires a supply of energy resources that is sustainable, available at reasonable cost and causes no or minimal negative effects. Fossil energy resources are finite, and thus lack the characteristics needed for stability and sustainability, while green energy sources are sustainable over the …
Since its discovery 150 years ago, petroleum oil has become lifeline of the world. The entire structure of the modern mechanized world, consisting from transportation system, automobiles, airplanes, railways, ships to space rockets today operates primarily on the energy derived from the fossil fuels/petroleum oils. …
Objective To determine the amount of oxygen necessary for biological oxidation of wastewater effluent and determine the amount of oxygen required by bacteria while stabilizing decomposable organic matter.

Chp. 15 Chemical equilibrium: Occurs when a reaction and its reverse reaction (opposing reactions) proceed at the same rate At equilibrium the rate at which products are produced from reactants equals the rate at which reactants are produced from products At equilibrium a particular ratio …
As industry developed and increased, as did the need for reliable and efficient fuels to power the new machinery developed. It did not take long before fossil fuels were discovered, with their innate ability to provide high amounts of energy at seemingly low costs. Fossil …
Nucleus: The nucleus is the most obvious organelle in any eukaryotic cell. It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics. The …
A1. Role of Enzymes in Processes Enzymes are organic catalysts that help to speed up the breakdown of a molecule, such as fructose. The enzyme helps a chemical reaction take place quickly so that the reaction happens properly. In order for that to happen the …
Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
