What is BIOLOGICAL PUMP? What does BIOLOGICAL PUMP mean? BIOLOGICAL PUMP meaning - BIOLOGICAL PUMP definition - BIOLOGICAL PUMP explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. The biological pump, in its simplest form, is the ocean’s biologically driven sequestration of carbon from the atmosphere to the deep sea. It is the part of the oceanic carbon cycle responsible for the cycling of organic matter formed by phytoplankton during photosynthesis (soft-tissue pump), as well as the cycling of calcium carbonate (CaCO3) formed by certain plankton and mollusks as a protective coating (carbonate pump). The biological pump can be divided into three distinct phases, the first of which is the production of fixed carbon by planktonic phototrophs in the euphotic (sunlit) surface region of the ocean. In these surface waters, phytoplankton use carbon dioxide (CO2), nitrogen (N), phosphorus (P), and other trace elements (barium, iron, zinc, etc.) during photosynthesis to make carbohydrates, lipids, and proteins. Some plankton, (e.g. coccolithophores and foraminifera) combine calcium (Ca) and dissolved carbonates (carbonic acid and bicarbonate) to form a calcium carbonate (CaCO3) protective coating. Once this carbon is fixed into soft or hard tissue, the organisms either stay in the euphotic zone to be recycled as part of the regenerative nutrient cycle or once they die, continue to the second phase of the biological pump and begin to sink to the ocean floor. The sinking particles will often form aggregates as they sink, greatly increasing the sinking rate. It is this aggregation that gives particles a better chance of escaping predation and decomposition in the water column and eventually make it to the sea floor. The fixed carbon that is either decomposed by bacteria on the way down or once on the sea floor then enters the final phase of the pump and is remineralized to be used again in primary production. The particles that escape these processes entirely are sequestered in the sediment and may remain there for thousands of years. It is this sequestered carbon that is responsible for ultimately lowering atmospheric CO2. The first step in the biological pump is the synthesis of both organic and inorganic carbon compounds by phytoplankton in the uppermost, sunlit layers of the ocean. Organic compounds in the form of sugars, carbohydrates, lipids, and proteins are synthesized during the process of photosynthesis: CO2 + H2O + light › CH2O + O2 In addition to carbon, organic matter found in phytoplankton is composed of nitrogen, phosphorus and various other trace metals. The ratio of carbon to nitrogen and phosphorus varies little and has an average ratio of 106C:16N:1P, known as the Redfield ratio. Trace metals such as magnesium, cadmium, iron, calcium, barium and copper are orders of magnitude less prevalent in phytoplankton organic material, but necessary for certain metabolic processes and therefore can be limiting nutrients in photosynthesis due to their lower abundance in the water column. Oceanic primary production accounts for about half of the carbon fixation carried out on Earth. Approximately 50-60 Pg of carbon are fixed by marine phytoplankton each year despite the fact that they comprise less than 1% of the total photosynthetic biomass on Earth. The majority of this carbon fixation (~80%) is carried out in the open ocean while the remaining amount occurs in the very productive upwelling regions of the ocean. Despite these productive regions producing 2 to 3 times as much fixed carbon per area, the open ocean accounts for greater than 90% of the ocean area and therefore is the larger contributor. The vast majority of carbon incorporated in organic and inorganic biological matter is formed at the sea surface and then must sink to the ocean floor. A single phytoplankton cell has a sinking rate around 1 m per day and with 4000 m as the average depth of the ocean, it can take over ten years for these cells to reach the ocean floor. However, through processes such as coagulation and expulsion in predator fecal pellets, these cells form aggregates. These aggregates, known as marine snow, have sinking rates orders of magnitude greater than individual cells and complete their journey to the deep in a matter of days.

    How accurate are 'skinfold' body fat tests that use callipers?
    98%
    The American College of Sports Medicine states that skinfold measurements, when performed by a trained, skilled tester, are up to 98% accurate. Because of the consistency in results, the high success rate, and the low margin of error, this is generally accepted as the best field test, outside of clinical testing, such as hydrostatic weighing.

    False
    Avoid wearing ankle and wrist weights. They can alter your normal movement patterns and increase the risk of injury. If you must add weight to your workout, a weighted vest helps distribute weight more evenly and allows you to move more freely and normally than weights attached to your extremities.

Biochemistry

Sort what is the regulation of the citric acid cycle The citric acid cycle is regulated mostly by substrate availability, product inhibition and by some cycle intermediates. • pyruvate dehydrogenase: is inhibited by its products, acetyl-CoA and NADH • citrate synthase: is inhibited by its product, citrate. It is also inhibited by NADH and succinyl-CoA (which signal the abundance of citric acid cycle intermediates). • isocitrate dehydrogenase and a-ketoglutarate dehydrogenase: like citrate synthase, these are inhibited by NADH and succinyl-CoA. Isocitrate dehydrogenase is also inhibited by ATP and stimulated by ADP. All aforementioned dehydrogenases are stimulated by Ca2+. This makes sense in the muscle, since Ca2+ release from the sarcoplasmic reticulum triggers muscle contraction, which requires a lot of energy. This way, the same "second messenger" activates an energy-demanding task and the means to produce that energy. What is the regulation of fatty acid metabolism Acyl-CoA movement into the mitochondrion is a crucial factor in regulation. Malonyl-CoA (which is present in the cytoplasm in high amounts when metabolic fuels are abundant) inhibits carnitine acyltransferase, Continue reading >>
