a) Calculate the enzyme and specific activity of a reaction with 3 μM Hsp90 using the following information: The rate is measured in a spectrophotometer as 0.028 OD units/min in a 1 ml reaction volume. The absorbance was detected at 340nm and the extinction coefficient for NADH at this wavelength is 6200 L M-1 min-1 and the molecular mass of Hsp90 is 82.7 kDa. The rate of NADH utilisation is equivalent to the rate of ATP utilised by Hsp90. Show all your calculations and the units for your answers. b) Calculate the turnover number for the reaction described in (a) above

A violation of the First Law? The complete combustion of glucose to CO 2 and H 2 O yields 30 ATP, as shown in Table 18.4 . However, the synthesis of glucose requires only 18 ATP. How is it possible that glucose synthesis from CO 2 and H 2 O requires only 18 ATP , but combustion to CO 2 and H 2 O yields 30 ATP? Is it a violation of the First Law of Thermodynamics , or perhaps a miracle?
Examine which of the following statement are FALSE about enzymes. * (Please choose one correct answer) A. The enzyme specificity of binding depends on the precisely defined arrangement of atoms in an active site suggesting for the lock-and-key mechanism B. The enzyme in an enzyme catalyzed reaction increases the rate at which the substrate is converted into product while lowering energy of activation C. First order reaction means S < Km while when S > Km means its zero-order reaction D. Glucose oxidase catalyzes the oxidation of β-D-glucose but not α-D-glucose is an example of absolute specificity E. One of the enzymes involved in the transport of oxygen from the lungs to the capillaries of the tissue requires Fe+ for catalysis. Under conditions of iron deficiency wherein the enzyme my lack iron, the enzyme would be referred to as the holoenzyme.
