Question

taken 1 hour 1 min If the substrate concentration is varied with a fixed concentration of enzyme, it is observed that allow substrate concentrationer overall order while at high substrate concentrations, the reaction will be overall order 00 Select one: a. first; second first; third order c. first; zero d. second: second e. second: pseudo first order Which statement is false about the heme group? of 1 50 estion Select one: a. If exposed to air, a the heme iron is readily oxidized, converting Feto Fe and can no longer bind oxygen b. The heme group is roughly planar in shape C. The heme group is tightly, but non-covalently, held in myoglobin inolecule. d. When oxygen binds to heme, the iron ion is oxidized from Fe to Fe e. The chemical structure of the heme groups in myoglobin and hernoglobin are identical. When [S] = Ky Select one:

Answer 1

Answer: (o) Frogt, zeno. - In the mitial stage of Any chemlal Reacten, Rate of Reaction is directly Proportional to the concentration. of the substrate means of we increase the concentration, Rate will also increase, 80 nitial stage is first order. After some time, Rate of Reaction become constant even we Increase concentration then rate will not Increase Further, so this is a zero order Reaction. ) 80 that option C is the correct Answer:-(e) The chemiecu structure of the beme groups in myoglobin ond bemoglobin are identical - - Hemoglobin contains fourheme init, each embedded in a globular protein sub init, These ar two type of protem. sub unit- & and ß moglobin contains only one heme unit sursanded by a globular protein, contaming seveo d-heliecel and six mon helical segments . so we com qay that the chemical structure of heme in my oglobin and hemoglobin is not identical, 80 that option 'e' is correct.
