Which of these statements about enzyme-catalyzed reactions is false?

#Section 2: General Biology

  1. At saturating levels of substrate, the rate of an enzyme-catalyzed reaction is proportional to the enzyme concentration.

  2. If enough substrate is added, the normal Vmax of a reaction can be attained even in the presence of a competitive inhibitor.

  3. The rate of a reaction decreases steadily with time as substrate is depleted.

  4. The activation energy for the catalyzed reaction is the same as for the uncatalyzed reaction, but the equilibrium constant is more favorable in the enzyme-catalyzed reaction.

A fermenter is maintained at 35⁰C by water circulating at a rate of 0.5 kg s^-1 in a cooling coil inside the vessel. The inlet and outlet temperatures of the water are 8⁰C and 15⁰C respectively. The length of the cooling coil is increased by 50%. In order to maintain the same fermentation temperature, the rate of heat removal must be kept the same. Determine the new cooling-water flow rate and outlet temperature by carrying out the following calculations. The heat capacity of the cooling water can be taken as 4.18 kJ kg^- 1 o C^- 1. Evaluate UA for the original coil. ________________
