Cell Chemistry (mod 2 SLP) - Essay specimenThe natural heat and intense pressure of the earth act on the mass and bacteria permute the matter into precursor centers for the formation of hydrocarbons. The hydrocarbons migrate to the surface through permeable rock layers or start out trapped in impermeable rock membranes (Simanzhenkov, 2003, pp. 14-16).Autotrophs are organisms that can make their own food from the on tap(predicate) 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 contact substances. Photosynthetic autotrophs also known as phototrophs make their own food by using high spirits energy to convert organic compounds to food. Chemosynthetic autotrophs also known as chemotrophs make their own food by using tripping energy to oxidize compounds such as Hydrogen sulphide.The first photosynthetic pathway, photophosphorylation, uses light energy to produce adenosine triphosphate 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 oxidisation 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
