(a)
To calculate: The time required to decompose the H2O2, in the presence of ferric ions equivalent to the iron content of 1 µg of catalase.
Introduction: Hydrogen peroxide is catalyzed by the enzyme catalase and converts it into water and oxygen molecule. Many ways can accelerate the rate of the hydrogen peroxide decomposition.
(b)
To calculate: The time required to decompose the same amount of H2O2, in the absence of a catalyst.
Introduction: Catalase is an enzyme which decomposes the hydrogen peroxide into hydrogen and oxygen. Ferric ions act as an inorganic catalyst and lower the activation energy of the reaction.
(c)
To explain: In what way these calculations illustrate the indispensability of catalysts and the superiority of enzymes over inorganic catalysts.
Introduction: Catalase is an enzyme which decomposes the hydrogen peroxide into hydrogen and oxygen. Ferric ions act as an inorganic catalyst and lower the activation energy of the reaction.

- ENZYME KINETICS ANALYSIS of 6 Xanthine oxidase (XO) is the enzyme that catalyzes the synthesis of uric acid, which in excess causes gouty arthritis. The inhibition of this enzyme is therefore critical in its treatment. A student researcher is investigating the inhibitory effects of kaempferol (Kmp) and chlorogenic acid (Cha) on XO which uses xanthine (Xan) as substrate. Table 1 below shows the enzyme kinetic data.

- not true about the Michaelis-Menten equation? The equation that gives the rate, v, of an the substrate concentration [S] is the Michaelis-Menten equation = Vmax[S]/(Km + [S]), where V, enzyme-catalyzed reaction for all values of max and Km are constants. Which of the following is a) for [S] << Km, V = Vmax applies to most enzymes, but allosteric enzymes have different kinetics when [S] = Km, then v = Vmax/2 gives the rate when the enzyme concentration, temperature, pH, and ionic strength are constant for very high values of [S], v approaches Vmax e) Which is correct about the constant Km in the Michaelis-Menten equation? also called the catalytic constant or turnover number equal to the number of product molecules produced per unit time when the enzyme is saturated with substrate it is the constant in the first order rate equation v = k[A] it is the constant in the second order rate equation v = equal to the substrate concentration at which the velocity or rate of a reaction is ½ the…arrow_forwardBiochemical events in the synthesis of ATP: I.

ATP synthesis in chloroplasts is usually light dependent; it does not happen in the dark. When researchers shifted isolated chloroplasts from a low pH solution to a more alkaline (higher pH) solution, ATP synthesis occurred even in the absence of light! This was an experiment used to support the chemiosmosis mechanism of ATP formation in chloroplasts. Why? What would happen if the isolated chloroplasts were shifted to a lower pH solution? What would be the results if the above experiments were performed in the presence of light? If these experiments were performed in mitochondria instead of chloroplasts, what results would we expect?arrow_forward
