initial rate enzyme

A large number of chemical reactions will be taking place in a cell. The rate and efficiency with which these reactions go on in a cell, depend on a group of macromolecules called enzymes. Enzymes are thus, biological catalysts. Enzymes are synthesised by li..

Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union of Biochemistry (IU..

Any chemical reaction requires a certain amount of energy to get initiated. This is called activation energy. Most of the molecules in a substrate have average kinetic energy, some have high energy and some have low energy. Under normal conditions of temperature only molecules with higher..

Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense catalytic power; they accelerate reacti..

Enzymes control several metabolic pathways and are highly specific in their action. Enzymes like invertase, zymase and maltase are used in manufacture of alcoholic drinks. Some enzymes are used as therapeutic agents. For e.g., streptokinase is used to dissolve ..

Initial Rate Method - This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants const..

Choose the exponential function with the initial value as 6, increasing at a rate of 48% per year. => S( t ) = (1.48) t or S( t ) = 6(1.48) t or S( t ) = 6(0.48) t or S( t ) = 6(1.16) t..

Choose the exponential function with the initial value 12, decreasing at a rate of 0.47% per week. => S( t ) = 47(0.0012) t or S( t ) = 12(0.0047) t or S( t ) = 12(0.9953) t or S( t ) = 47(0.0995) t..

But for having unique value of the reaction rate (independent of the concentration term chosen), we divide the rate of the reaction, defined with respect to any of the reactants or products by the number of moles involved in the reaction. Thus, for the above reaction, rateh..

Jim deposited some amount in a bank at a rate of 3% compound interest. What was the amount deposited initially, if the balance in his account at the end of 5 years is found to be $3000? => $2826.35 or $2485.45 or $2686.45 or $2586.20..
