    that environment does not stay constant the organisms might not be able to function due to their specialization. If the environment is in a state of disarray, i.e., homeostasis is not maintained, then the enzymes could be denatured as a result. 2. A reaction you are monitoring is catalyzed by an enzyme. You start recording data at a low temperature, and gradually increase the temperature (not stopping until you reach the boiling point of water). Describe each of the…

    (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when temperature is above 100°C This led them to conclude that the oxidation is a mixed controlled reaction. Alkaline oxidation of arsenic bearing minerals Arsenopyrite (FeAsS) is the most abundant arsenic containing sulphide mineral. As such, it will be the focal point…

    approximately at 40℃. This result was expected as this trial temperature was closest to internal body temperature, 38℃, and as catalase is present in all body organs (T. Fouad, Antioxidants). Temperature affects chemical reactions by increasing the kinetic motion of molecules and changing the rate of collisions between them. In lower temperatures, kinetic motion is decreased and there are not enough collisions between the molecules for enzyme activity to be maximized. However, as temperature…

    are catalysts that contain proteins. Catalysts are the part of the product that speeds up a reaction. Only reactions can occur when the right enzyme ends up finds the right material to produce a process. A low pH is a good environment for an enzyme as well as a low temperature. After the reaction, no enzymes are used up. They can be used again and again in reactions, once an enzyme is used in one reaction, it can be used in another. Enzymes are made up of proteins and proteins are made of of…

    1. Redox Catalyst Catalyst is defined as a substance that increases the rate of a chemical reaction without changing its chemical composition and affecting the standard Gibbs free energy, by lowering the activation energy of a chemical reaction. It does so by providing an alternative reaction pathway. In redox reaction, the key chemical event is the net movement of electrons from one reactant to the other. The oxidation state of atoms are changed. Transition metal is used as redox catalyst due…

    Many factors can affect how fast an enzyme is able to change the state of a solution. Enzymes are proteins that act as catalysts, they allow reactions to be sped up by allowing the reaction to occur with a lower activation energy. Normally for a reaction to occur the molecules of each substance must collide with each other with enough energy to start the reaction. Enzymes function to remove this part of the process and interact with both substrates. Invertase is an important example of such an…

    proteolytic enzyme, important for the digestion of proteins. Enzymes are biological catalysts for metabolic process in cells. A catalyst is a substance that changes the rate of a reaction. Enzymes act as catalysts for chemical reactions in the body. Enzymes are large proteins that are not consumed or changed in a chemical reaction. They are highly specific to the substrate - the substance an enzyme acts on - they act upon. When an enzyme is available with an empty active site, the substrate…

    effect the rates of most biological reactions and biological processes in ectotherms. The rates of ontogenetic growth and development are no exceptions. Ectothermic animals develop faster at warmer temperatures and they usually mature at smaller body sizes. This phenomenon has been called the temperature size rule (Zuo et Al. 2011). The temperature size rule is a necessary outcome of differences in the temperature dependence of somatic growth rate and development rate, thus proving rates of…

    the enzyme catalyzed biological reactions are reversible in nature. However, an enzyme may prefer to catalyze the reaction more efficiently in one direction over the other under given physiological concentrations of substrate or product (substrate in the reverse direction). An enzyme favouring a virtual unidirectional catalysis of an overall reversible reaction can’t escape the laws of thermodynamics. As a catalyst doesn’t change the equilibrium constant of a reaction but only modifies the…

    between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to carry on the reaction. Stoichiometry can definitely be named…
