Which of the following protein is not synthesized by membrane-free ribosomes?

Which of the following protein is not synthesized by membrane-free ribosomes? Correct Answer Extrinsic membrane proteins localized to the extra-cytoplasmic surface

Extrinsic membrane proteins localized to the extra-cytoplasmic surface are not synthesized by membrane-free ribosomes. ER membrane-bound ribosomes synthesize the extrinsic membrane proteins that are localized to the extra-cytoplasmic surface. Chloroplast proteins, peroxisomal proteins, and extrinsic membrane proteins localized to the cytoplasmic surface are synthesized by membrane-free ribosomes.

Proteins that are to be incorporated into cytoplasmic organelles are synthesized on ER membrane-bound ribosomes. Whereas, proteins that are to be imported into the ER-Golgi system are synthesized on free ribosomes in the cytosol.
Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:
Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.
