...? BIOCHEMISTRY Task: Outline i. Introduction ii. iii. Apoptosis iv. Death of mature immune cells v. Apoptosis in clinical immunology vi. Conclusion References The biochemistry of apoptosis Introduction The recognition of the death of cells by apoptosis has existed for many years. The full explanation of the biochemistry of apoptosis, that has surfaced for years is nothing short of astonishing, and has changed our perceptions about diseases. Usually, the categorization of ailments has been in accordance of the organ system they affect. Nevertheless, it is useful for researchers to discover the system responsible for the diseases. In this respect, the simple reclassification according to...

...? Clinical Cases; Questions and Answer Part Case Study Glycaemic status Question Blood glucose monitoring has been an important tool in the effective management of out-patients with diabetes. This tool which entails self monitoring of blood glucose level in a specified period has been designed to help in glycaemic control and lowered the risk associated with high blood sugar level. Considering the result of the biochemical analysis done for the patient, it can be concluded that the patient has not been monitoring his blood sugar effectively. Each of those outlined results point towards different analysis and help in the assessment of a poorly controlled blood sugar. Fasting blood glucose clearly shows a higher value that is far...

... A female patient, 11 weeks old, presents the following symptoms; an enlarged liver and spleen and failure to thrive. You order a liver biopsy that indicates she exhibits early stages of liver cirrhosis and histological studies (see image below) show a periodic acid-Schiff (PAS)- positive (indicates presence of glycogen), amylase-resistant, coarsely clumped material in the liver cells that is consistent with abnormal and insoluble glycogen. Explain the most likely metabolic basis for the child's symptoms and identify the metabolic disorder she presents. The above mentioned symptoms correlate with the disorder 'Glycogen storage disease type IV', also known as "Andersen's disease... A female...

...BIOCHEMISTRY DISCUSSIONS Assignment 10 November The Central Dogma of Biochemistry and How it Affects Humans The central dogma of biochemistry states that the stream of information in living organisms starts from DNA to RNA and finally to proteins (Mikulecky, Gilman & Peterson, 2008). This means that the existence of information relies on its movement from the genetic material (DNA) to RNA (coded genetic information) and finally to proteins. The three steps involved in the central dogma are replication, transcription, and translation. Replication is the copying of genetic material, which leads to the establishment of more than one copy of DNA. Transcription is the process that produces RNA from DNA, and translation is the synthesis...

...Biochemistry Case of In normal muscle activity, glucose is transported through blood stream from liver to muscles. This glucose is actually the product of glycogenolysis and provides muscle with Adenosine tri-phosphate (ATP) which is the basic energy currency for the cell. Pyruvate is the end product of this process when energy is sufficient but during the time of hypoxia this pyruvate goes into lactic acid cycle. It is conversion of pyruvate into lactate to produce extra amount of energy which is 2 molecules of ATP’s. The enzyme involved in this process is called lactate dehydrogenase. This lactate is normally takes back to liver where it would convert back into pyruvate and glucose through process of gluconeogenesis....

...Biochemistry Assignment How glutamic acid (glutamate) act as an excitatory neurotransmitter Amino acid group contains the universal excitatory transmitter called Glutamate.Glutamate acid is the most dominant excitatory transmitter in the central nervous system. Neurons from glucose are responsible for the synthesis of glutamate. It plays its role by opening sodium Na and potassium K channels. Upon its release, glutamate is conveyed from the synaptic cleft either to adjacent neurons or into the nearby glial cells. Those neurons that produce glutamate at their Synaptics are are called glutamatergic. The principal effect of glutamate in the central nervous system is the fast excitation through direct action...

...Q1. Define the term “Posttranslational modifications” and give at least two examples of different types of posttranslational modifications. Synthesisof protein molecules occur through the process of translation which is a m-RNA mediated mechanism. The process encompasses various enzymatic methods in order to certify that proteins formed in the process of translation are accurate, with proper folding and are ready to perform their assigned functions namely as enzymes, antibodies, hormones etc. The process of translation is followed by numerous modifications in the covalent bonds leading to the alteration in the properties of proteins; such alterations are known as post-translational modifications (PTMs). The process...

... Reasons of adding Vitamin C to collagen in cosmetics Role of vitamin C in collagen synthesis is a vital constituent in the skin health. Vitamin C plays an important role on the skin cells and studies have shown that photodamage induced by ultraviolet light are treated by Vitamin C. Although Vitamin C is not sunscreen it is used to provide antioxidants and proteins keratinocytes that are used to protect the skin (Mason 19). Vitamin C is among the ingredients used in skin care. Vitamin C is used in the synthesis of collagen which is an important structural compound of the skin. This helps in wound healing by promoting differentiation of keratinocytes thus stimulating formation of epidermal barrier and stratum corneum. Vitamin C... Reasons of...
