Cholera is an infectious disease with diarrhoea caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. Cholera was prevalent in the UK in the 19th century before modern water and sewage treatment systems eliminated its spread by contaminated water.
Different chemical reactions are used in combinations during chemical synthesis in order to obtain a desired product. In biochemistry, a consecutive series of chemical reactions (where the product of one reaction is the reactant of the next reaction) form metabolic pathways. These reactions are often catalyzed by protein enzymes.
A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale.The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials.hemical plants use chemical processes, which are detailed industrial-scale methods, to transform feedstock chemicals into products. The same chemical process can be used at more than one chemical plant, with possibly differently scaled capacities at each plant.
