Cellular Metabolism Metabolism is the process of converting energy from a stored form (e.g. The energy from photosynthesis and metabolism can be used to do work such as building molecules of the body structure and creating movement. To summarize, all forms of life show metabolic activity; they extract and transform energy from their environment and use it for manipulating materials in ways that assure their own maintenance, growth, development and reproduction. www.msc.cc.ok.us /~bstewart/bstewart/classes/biology/metabo.htm   (995 words)

Metabolism: Cellular Respiration Cellular respiration is the process by which food molecules react with oxygen and are broken down to carbon dioxide and water with a net gain of captured energy in the form of ATP molecules. The cellular process used for the initial breakdown of 6-carbon sugars is called GLYCOLYSIS and occurs in the CYTOSOL of the cell. In animals, as this OXYGEN DEBT is paid off by increasing amounts of oxygen becoming available, the lactic acid is converted to glucose in the liver, transformed to glycogen in muscle and oxidized to pyruvic acid and CO and sent to the Krebs cycle to complete the aerobic process. www.angelfire.com /ga2/nestsite2/webunit8.html   (1565 words)

Homocysteine   (Site not responding. Last check: 2007-11-05) Metabolism of the amino acid methionine, a limiting amino acid in the synthesis of many proteins, affects several biochemical pathways involving the production of nutrients which are essential to the optimal functioning of the cardiovascular, skeletal, and nervous systems. The metabolic pathways of betaine, methionine, methylcobalamin, and 5-methylTHF are interrelated, intersecting at the regeneration of methionine from homocysteine. Because homocysteine metabolism, through the re-methylation and trans-sulfuration pathways, affects several biochemical pathways involving the production of nutrients which are essential to the optimal functioning of the cardiovascular, skeletal, and nervous systems, it is not surprising these other nutrients have been linked to complications of pregnancy in animal models and humans. www.thorne.com /altmedrev/fulltext/homo2-4.html   (8794 words)

Equine Nutrition Menu   (Site not responding. Last check: 2007-11-05) By determining the exact genetic problem and how it interferes with cellular metabolism, she has found it is often possible to provide a product which will replace the missing enzyme or other metabolic substance to allow cellular metabolism to function normally. There is also the possibility that the substance might interfere with normal cellular metabolism by providing too much of a good thing in normal horses, yet enhance cellular metabolism in horses genetically deficient in that substance. Applied nutrition is the feeding of products, many of which are natural substances involved in cellular metabolism, and thus come under the definition of food substances from one point of view. www.neosoft.com /~iaep/pages/nutritionmenu.html   (808 words)

Cellular Metabolism The basal metabolic "rate" is the power required to sustain those functions. For instance, two thirds of your basal metabolism is required to move ions against concentration gradients (see Chapter 4).
