Cell Chemistry (mod 2 SLP) - Essay Example The natural heat and intense pressure of the earth act on the mass and bacteria convert the matter into precursor substances for the formation of hydrocarbons. The hydrocarbons migrate to the surface through permeable rock layers or get trapped in impermeable rock membranes (Simanzhenkov, 2003, pp. 14-16). Autotrophs are organisms that can make their own food from the available substances through photosynthesis or chemosynthesis while Heterotrophs are organisms that cannot make their own food and thus depend on other organisms including plants and animals for food. Examples of Autotrophs are algae, plants and certain bacteria. Examples of Hetetrophs include omnivores, carnivores and herbivores. Both photosynthetic autotrophs and chemosynthetic autotrophs organisms produce their own food from the surrounding substances. Photosynthetic autotrophs also known as phototrophs make their own food by using light energy to convert organic compounds to food. Chemosynthetic autotrophs also known as chemotrophs make their own food by using light energy to oxidize compounds such as Hydrogen sulphide. The first photosynthetic pathway, photophosphorylation, uses light energy to produce ATP and reduction electron carrier, NADPH+ H+. Nitrogen fixation reduces atmospheric nitrogen into ammonia. Both photophosphorylation and nitrogen fixation are reduction pathways. The Nitrification process is an oxidation pathway that produces nitrate from the oxidation of ammonia and the second photosynthetic pathway, Calvin-Benson cycle is also an oxidation process uses energy from NADPH+, H+, ATP and carbon dioxide to produce carbohydrates. Bioassay is a test used to measure the effects of a substance to living things. The procedures determine purity concentration and biological activity of substances. The scientists used a bioassay in the study since assays are acute
