The Great Metabolic Race Organisms are constantly undergoing various chemical reactions and pathways that enable for them to maintain life. These pathways are part of metabolism‚ involving catabolism (break down of organic nutrients for extraction of useful) and anabolism (energy dependent conversion of small precursor molecules in complex molecules); some of which are energy coupled to provide energy efficiency. This intermediate coupling is due to the “energy currency” within the body‚ known as

Drosophila virilis‚ as well as a marker strain (mutant strain of D. melanogaster) were used to examine the genetic variation. Electrophoresis followed by the staining of the proteins will cause the enzymes‚ aldehyde oxidase‚ alcohol dehydrogenase‚ and malate dehydrogenase‚ to become visible‚ appearing as a set of different banding patterns. The banding patterns will dependent on the molecular form of the enzyme‚ indicating the genetic variation that can exist between strains (Biology Department‚ 2014)

1.0 Introduction This assignment is based on a study of alcohol metabolism and its impacts to human health. The assignment explains that how the body can dispose of alcohol and discern some of the factors that influence this process and influences of the process to the metabolism of food‚ hormones‚ and medications. 1.1 History of alcohol The word “alcohol” appears in English as a term for a very fine powder in the 16th century. It was borrowed from French‚ which took it from medical Latin.

acetyl CoA is able to enter the citric acid cycle because this is the most acceptable fuel input into the cell. The path that the pyruvate takes depends on the energy needs of the cell and the oxygen availability (Tymoczko‚ p. 318). Pyruvate dehydrogenase complex consist of three distinct enzymes each with its own active

In fat synthesis‚ the enzyme pyruvate dehydrogenase‚ which forms acetyl-coA‚ and also acetyl CoA carboxylase which forms malonyl-coA are obvious control points. These are activated by insulin. This leads to an overall increase in the levels of malonyl-coenzyme A‚ which is the substrate required for fat synthesis. Thus‚ the flux down storage pathway is increased when there is sufficient glucose in the ’fed’ state. Pyruvate dehydrogenase dephosphorylation Pyruvate dehyrdrogenase

Introduction All tissues have some capability for synthesis of the non-essential amino acids‚ amino acid remodeling‚ and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen. However‚ the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus‚ the potentially toxic nitrogen of amino acids is eliminated via transaminations‚ deamination‚ and urea formation; the carbon skeletons are generally conserved as carbohydrate
