CSIR NET Life Sciences Biochemistry Questions with Answer Key

Enzymes accelerate a reaction by which one of the following strategies? (CSIR_2015_II)

Coupling of the reaction centers of oxidative phosphorylation is achieved by which one of the following? (CSIR_2015_II)

Glycophorin having one highly hydrophobic domain is able to span a phospholipid bilayer membrane only (CSIR_2015_II)

Following is the domain organization of three proteins that are targeted to the mitochondria.

Based on the domain organization in the above figure and assuming the left box to be having the mitochondrial sorting signal, predict the most likely sub-compartment of the mitochondria in which the protein will be found. (CSIR_2015_II)

Which one of the following statements is correct? (CSIR_2015_II)

A protein has 4 equally spaced trypsin sensitive sites which results in peptide fragments A1, A2, A3, A4 and A5 upon digestion with trypsin. The peptides A2 and A5 represent N-terminal and C-terminal fragments respectively. Now you are asked to synthesise this protein. At time t = 0 you added all the 20 amino acids labeled with 14C and initiated the synthesis. At time t = 4, full length protein is synthesized. If you stop the synthesis of the protein in time t = 1 and digest the protein with trypsin, which peptide will have maximum 14C label than others? (CSIR_2015_II)
