Question
1.True (T) or False (F)? (1) AG of protein unfolding is positive. (2) Immunoglobulin is composed of 2 polypeptide chains. (3) Lipid can be an antigen. (4) Vmax can be increased by decreasing [S]. (5) Polyclonal antibody is a protein that can bind to different regions of an antigen (6) There are many ester bonds in lipase. 7) Viral surface protein can be a vaccine. (8) Vmas of enzyme reaction is not changed by adding non-competitive inhibitor. (9) Bacterial cell is better than animal cell for the production of bacterial protein. (10) Ethane moves faster than methane in hydrophobic chromatrography. (11) Mass spectroscopy can be used to analyze the protein sequence.Explanation / Answer
1) protein folding is a spontaneous process which makes unfolding a non-spontaneous process and delta G is +ve.TRUE
2) immunoglobulin molecules are glycoproteins composed of one or more units each containing 4 polyoeptide chains : two identical heavy chains and two identical light chains. Given statement is FALSE.
3) lipid can an antigen. TRUE . There are antigenic lipids.
4) Vmax can be increased by decreasing [S] . FALSE.
