Following are certain statements regarding activated and inactivated form of Rubisco, Which one is INCORRECT?

#Section 2: General Biology
  1. The naturally occurring inhibitor 2-carboxyarabinitol 1-phosphate prevent activation of Rubisco
  2. plant rubisco active site contains His, Asp, Glu and Lys 201 , is a carbamoylated Lys 201 side chain with a bound Mg 2+ ion and is absoluetly require for its activation
  3. The increase in both pH and concentration of Mg2+ facilitates the formation of the (E–NH 3 + – CO2 – • Mg2+) complex, which represents the catalytically active form of rubisco
  4. The tight binding of sugar phosphates, such as ribulose 1,5-bisphosphate (RuBP), either impedes the production of the E–carbamate adduct or blocks the binding of substrates to the carbamylated enzyme

#Section 4: Fundamentals of Biological Engineering

A fermentation slurry containing Streptomyces kanamyceticus cells is filtered using a continuous rotary vacuum filter. 120 kg h- 1 slurry is fed to the filter; 1 kg slurry contains 60 g cell solids. To improve filtration rates, particles of diatomaceous-earth filter aid are added at a rate of 10 kg h- 1. The concentration of kanamycin in the slurry is 0.05% by weight. Liquid filtrate is collected at a rate of 112 kg h-1; the concentration of kanamycin in the filtrate is 0.045% (w/w). Filter cake containing cells and filter aid is continuously removed from the filter cloth.
 What percentage liquid is the filter cake?

If the concentration of kanamycin in the filter-cake liquid is the same as in the filtrate, how much kanamycin is absorbed per kg filter aid?.,..... 10-4
