During a race‚ there is an inherent increase in energy requirements and these requirements are maintained by the many biochemical events happening within the body. This essay explores the metabolic processes that occur at the start of the race‚ 5 minutes into the race and 45 minutes into the race in terms of mobilization‚ biochemical pathways used for degradation of molecules and comparing the yield of ATP of the two types of fuels involved‚ namely carbohydrates and lipids. Carbohydrates‚ which have

reaction or process that releases energy in the form of heat. Sometimes the term is applied to processes that release other forms of energy‚ such as electrical energy‚ sound‚ or light. An Example –The example would be combustion of wood. Oxidation - Oxidation is the loss of electrons during a reaction by a molecule‚ atom or ion. An Example - The example is iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. Heating natural gas - Natural gas is a

disproportionation reaction). The solution remains strongly basic. The chemical equation for the process is: Cl2(g) + 2OH- (aq) ---> ClO- (aq) + Cl- (aq) + H2O (l) The amount of hypochlorite ion present in a solution of bleach can be determined by oxidation-reduction titration. One of the best methods is the iodine-thiosulfate titration procedure. Iodide ion‚ I-‚ is easily oxidized by almost any oxidizing agent (It has many electrons to lose!). In an acid solution‚ hypochlorite ions oxidize iodide

When rounding calculated numbers‚ we pay attention to significant figures so we do not overstate the accuracy of our answers. Rules: -All nonzero digits are significant. -Zeroes between two significant figures are themselves significant. -Zeroes at the beginning of a number are never significant. -Zeroes at the end of a number are significant if a decimal

This process is known as ___________. 7. All of the reactions of glucose oxidation that follow glycolysis involving the transfer of electrons to their final acceptor‚ oxygen‚ take place in eukaryotic cells in the ___________. 8.

used COD as a source of organics for denitrification. In the next 2 hours of aeration‚ ammonium was oxidized faster than COD and reached 89%. This was a result of the increase in DO concentration that exceeded 6 mg/L. The increase in DO made the oxidation of NH4-N unlimited.
