Redox

Parthenolide and STAT: It is previously discussed that the activation of STAT directs to cell proliferation, cell migration, transformation, apoptosis, cellular differentiation, adhesion, fetal development, inflammation, and immune response. In normal homeostasis, STAT tyrosine phosphorylation is short-term, lasting from 30 minutes to several hours, where as in numerous cancer cell lines and primary tumors it is in contrary to that of normal homeostasis. It takes place due to the deregulation of…

Measuring the mass of Iron in an iron sulphate tablet using REDOX titration Aim The aim of this experiment is to determine the mass of iron present in one iron sulphate tablet using REDOX titration under acidic conditions. Safety H2SO4: This is an irritant which may cause burns on skin and eyes; therefore care must be taken when handling this chemical. Protective gear (gloves, lab coat and safety goggles) must be worn at all times. If it comes in contact with skin or eyes, it should be…

reactant side. An example of this is seen when methane gas is burned in the presence of excess oxygen: CH4 + 2O2 → CO2 + 2H2O. Another reaction is Redox. Redox is an abbreviation of reduction/oxidation reactions. It is when one species is reduced and another is oxidized. Reduction involves a gain of electrons and oxidation involves a loss, so a redox reaction is one in which electrons are transferred between species. Single-Replacement Reactions is when a chemical change where one element…

Aim: - To Study about types of chemical reactions such as combination, decomposition, displacement and double displacement. - Find out about oxidation and reduction (redox reactions). II. Definitions: 1. Combination reactions: Combination reactions are reactions in which two reactants combine to form one product. For example: when a metal undergos a combination reaction with oxygen, a metal oxide is formed. 2…

to aerobic process Is exergonic and has a free energy change of -686 kcal/mol of glucose Redox reactions: oxidation and reduction Oxidation-reduction - or redox reactions, involve partial or complete transfer of 1 or more electrons from 1 reactant to another Oxidation - loss of…

What is the origin of life? This inquisition has baffled scientists and researchers since the beginning of time. While each new discovery gives a small notion for where and how life on Earth began, the newest clue is the discovery of hydrothermal vents. These vents are deeply immersed in the oceans that harbour rich ecosystems, the energy source from mid-ocean-ridge volcanism. Additionally the vents can reach high temperatures up to 407C (Sander, 2011). and can reach temperatures up to 121°C…

electroactive species is the same at differ-ent scan rates. If the peak current increases linearly with the scan rate, then it is reasonable to say that it is a diffusion-controlled (reversible) reaction. According to Fig. 2, the reaction is an irreversible redox reaction at the electrode electrolyte interface at low sweep rate. This irreversible nature of the electrode reduces the charge-transfer processes at the interface. We believe that this is a possible reason for the decrease in the…

another and eventually used to generate a large amount of ATP by oxidative phosphorylation. Oxidative Phosphorylation is the process that uses energy derived from the redox reactions of an electron transport chain. An electron transport chain is a sequence of electron carrier molecules that shuttle electrons down a series of redox reactions that release energy used to produce the ATP. All cells require ATP to function properly, and just about all of them use cellular respiration to produce it.…

maintenance of redox potential in cells and NADPH produced by G6PD acts as the cofactor for anti-oxidant enzymes including glutathione reductase, which reduces glutathione. Reduced glutathione functions as the cofactor for the glutathione peroxidase and the reduced glutathione and glutathione cycle indirectly play a crucial role in neutralizing hydrogen peroxides and lipid peroxides.10 Various literatures also highlight that G6PD is the main enzyme in cell death and intracellular redox…

Introduction Ascorbic acid is a form of vitamin C that is used by the body as a means of promoting healing of cuts and wounds, as well as boosting the immune system and as such aiding in the fight against infections. Ascorbic acid does not occur naturally and is formed by carrying out a variety of chemical reactions on corn syrup. The chemical formula for ascorbic acid is C6H8O6 and is similar to glucose which has a formula of C6H1206, this closeness in structure allows most animals (excluding…
