Consider the following statements and choose the correct answer:
1. The outer membrane of the nuclear envelope forms vesicles by 'blebbing'
2. The Golgi membranes have been variously described as originating from the plasmalemma nuclear envelope, annulate lamellae and ER
3. Vesicles arising from the Golgi complex fuse to form the plasmalemma
4. The Golgi complex cisternae form primary Iysosomes by blebbing
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:
Consider the following statements related to Swinepox. 1. Swinepox is a worldwide disease of pigs caused by a virus of the family Poxviridae and the genus Suipoxvirus. 2. Symptoms include small circular red areas 10-20mm in diameter that commence with a vesicle containing straw-coloured fluid in the center. 3. After two to three days the vesicle ruptures and a scab is formed which gradually turns black. Which of the following statement is/are correct?
Name the coated vesicle which is used to transfer protein from plasma membrane to endosome?
The protein coated vesicle must release its components into the Cytosol before fusing with the target site.
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.
