The Chemistry of Photography1

Photography is a very complex form of art, which uses standard chemicals and scientific equations. It is a chemical reaction, which occurs when light hits a film or paper emulsion. An emulsion is part of the film or paper, which is very sensitive to light. This is also the part where the chemical reaction takes […]

Organic Chemistry

Alcohols are generally represented by the formula R-OH (Elsheimer, 2000). R represents an alkyl group. Alcohols are classified as primary secondary or tertiary. Alcohols compounds have a hydroxyl group bonded to an sp3 hybridized carbon article. The most common alcohol compound is ethanol.These compounds have a hydroxyl group bonded to an aromatic hydrocarbon group. The […]

Biochemistry Sapling Glycoloysis, Gluconeogenesis

In glycolysis, why is MgATP used instead of just ATP for the hexokinase reaction? -Mg2 shields the negative charges of two of the phosphate oxygen atoms of ATP. -Mg2 makes the γ (terminal) phosphorus atom of ATP more accessible to nucleophilic attack by a glucose -OH group. The galactose derivative that enters the glycolytic pathway […]

An investigation into whether varying light intensity at a stream affects the species diversity

Foulden common has a variety of different habitats including grassland, young woodland, ponds, swamps, fenland, set-a-side and streams which enables a diverse range of organisms to be present in an area. Life for plants and animals in any medium is a constant struggle. Besides the physical environment, predators, parasites and other competitors that have to […]

What is Biofuel

Biofuels are produced from vegetable matter and they account for 15% of the world’s energy production. These are mainly used in LEDC’s(Less economically developed countries) for cooking and heating. For example oilseed rape can be converted into biodiesel fuel. Now scientists are interested in biofuels for transport.Italy produces some of it’s diesel form rape seed […]
