SHOW MORE The CAMP formed by adenyl cyclase does not persist because 5'-Phosphodiesterase activity prevalent in cells hydrolyzes CAMP to give 5'-AMP. Caffeine inhibits 5'-phosphodiesterase activity which promotes the presence of the more active 'a' form of Glycogen Phosphorylase. a If no precautions are taken blood that has been stored for some time becomes depleted in 2-3 BPG which will result in

Which of the following statements is/are TRUE?

Which of the following statements is/are TRUE? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation... SHOW MORE v The CAMP formed by adenyl cyclase does not persist because 5'-Phosphodiesterase activity prevalent in cells hydrolyzes CAMP to give 5'-AMP. Caffeine inhibits 5'-phosphodiesterase activity which promotes the presence of the more active 'a' form of Glycogen Phosphorylase. a If no precautions are taken blood that has been stored for some time becomes depleted in 2-3 BPG which will result in increased binding of 0, to Hemoglobin with decreased release of 02 to tissues. Sickle-cell anemia is the consequence of HbS polymerization through hydrophobic contacts between the side chain Vala6 and a pocket in the EF corner of a-subunits. d Decreasing the free energy of activation decreases the reaction rate. e The catalytic efficiency of an enzyme cannot exceed the diffusion rate of encounters between E and S. f When [S] = Km the velocity = Vmax/2. Lineweaver-Burk double reciprocal (1/V vs. 1/S) plots convert the hyperbolic Michaelis-Menten V vs. S plot into a straight line. According to the Michaelis-Menten equation the v/Vmax ratio = 0.4 when [S] = 4 Km. i If V, = 100 umol/mL/sec and Km = 2 mM the velocity of the reaction when [S] = 20 mM is 10 µmol/mL/sec. max
