Cori cycle



Dramatically explained cori cycle


Cori cycle is the metabolic process of converting lactate to glucose in the liver. This picture indicates how this take place. In rapid contraction of muscles produce lactate which then moves to the liver through blood stream. Converted glucose moves to the muscle via blood glucose. In the muscles glucose is converted to glycogen for storage, which is utilized when need be by rapid muscle contraction.  Glycogenolysis is the process of synthesis of glycogen. The process of glycogenolysis takes place as shown in this picture.



 Importance of cori cycle are; (1) Prevent acidosis in muscles, (2) Produces ATP. The production of ATP in this is important since can be utilized in the glycolytic pathway hence increase additional step.

How to write a Forensic Case Study: Murder of Junko Furuta

Image
Photo of Junko Furuta  For one to score high marks in a Forensic Case Study, one must  adhere to the following: Background of the case: This section contains details about the crime. It includes; the reasons for committing the offense, the conditions which the crime was committed, the circumstances of the crime scene and clear identification of the suspect(s) and the victim(s). One should ensure that the information in this part gives a precise idea of what the case is all about.   Pick and Write an article on Iwriter Website Evidence: This encompasses the piece of evidence found at the crime scene. The evidence should be described in details, that is, ways in which the evidence was collected, processed and preserved.   Forensic Tests: The tests should be two or more that were used to analyze the evidence. The science or theory of instrumentation used must be described fully.   Results: This consists of a detailed explanation of the forensic tests and the data inter

Roles of Sodium Carbonate when Extracting Caffeine from Tea Leaves

Image
A student failed to add sodium carbonate (Na 2 CO 3 ) when extracting caffeine from tea leaves with hot water. Though, high yield of caffeine was produced. The crystals melted at temperatures between 202  and 214 degree  Celsius. Explain. This happened because sodium carbonate did not interfere with the caffeine content of the tea leaves. Sodium carbonate (which is a base) deprotonates the phenolic hydroxyl group (-OH) (acidic) of tannins rendering them anionic. Hence, making them highly soluble in water, but parsimoniously soluble in methylene chloride. So, if sodium carbonate is not added when extracting caffeine with hot water, the extracted caffeine would also contain tannins. Additionally, sodium carbonate is added during the extraction to keep caffeine (an alkaloid which is an organic base)  in a free base form. It prevents caffeine from reacting with available acid available, which may lead to the formation cation. It reacts with a phenolic hydroxyl group

Arrhenius equation: Increasing temperature increases the rate reaction

Image
The rate of reaction of a particular reaction often increases as one increase the temperature. However, how can this belief be proved using Arrhenius equation? According to the Arrhenius equation, the rate constant (k) is obtained by the ratio of Ea to RT, in which Ea denotes required energy while RT is the available thermal energy. The Arrhenius Equation is given by: k=Ae - (Ea/RT) When Ea is larger, it results in slower reactions. On the other hand, when RT is large, it leads to faster rate of reaction. Larger Ea gives smaller rate constant k, but larger RT produces larger rate constant (k). Larger rate constant increases the rate of reactions.  By using Arrhenius equation, one can easily see that when the temperature is increased, the rate constant will also increase. Let us consider these two scenarios. In the first scenario, Ea=120,000 Joules/mole, R=8.31 mol -1 K -1 , and K=373K.In the second scenario, Ea=120,000Joules/mole, R=8.31 mol -1 K -1 , and K=423
