Oxygen Revolution {text:bookmark-start} {text:bookmark-end} Oxygen Revolution {text:bookmark-start} {text:bookmark-end} Oxygen Revolution The oxygen revolution‚ which is sometimes known as the oxygen catastrophe is believed to have occurred about 2.4 billion years ago with the evolution of cyanobacteria‚ a type of blue- green algae. Before this time‚ the atmosphere had a very different chemical make-up‚ high in carbon molecules; unsustainable for life as known today. These prokaryotes

Metallobiomolecules METALLOBIOMOLECULES CONTENTS 1. Introduction Metallobiomolecules 2. Classification Metallobiomolecules 2.1. Transport and of to Storage Proteins 2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this‚ new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful

“How humans impact the Carbon‚ phosphorus‚ and nitrogen cycles” Christine Richardson Environmental Science May 1‚ 2013 The carbon cycle is based on carbon dioxide which is a very important element because it is a part of all life. All living things are made of elements such as oxygen‚ carbon‚ hydrogen‚ nitrogen‚ calcium‚ and phosphorus. There are such compounds that are necessary for life such as sugars‚ fats‚ proteins etc. that joins with carbon to form these essential

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the
