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.

Protein’s solubility depends on the relative balance between protein-solvent and protein-protein interactions.
Many protein bars often contain protein supplements embedded in them, and sometimes provide upto 99% of the protein required. Nevertheless, a well balanced diet, which has an appropriate amount of all nutrients, is key to living a healthy life. Which of the options would support this statement, the best?
The statement given below is followed by two arguments. You have to decide which argument(s) is/are strong. Statements: Food rich in protein is better than junk food. Arguments: I.

For two hybrid systems, activation domains can be present in different proteins also rather than being on a single protein. A sequence encodes _______ protein for which we want to find an interacting protein.
An alternative approach to determining protein–protein interactions is to use a large-scale affinity purification technique that involves attaching fusion tags to proteins and purifying the associated protein complexes in an affinity chromatography column.
