Glycogen is abundantly present in which of the following tissues?

Given below are two statements:
Statement I: Haemoglobin and methaemoglobin are intracellular electron carriers in RedOx reactions to drive ATP synthesis.
Statement II: Isoprenoids( Ubiquinone, CoQ, Plastoquinone) are lipophilic electron carriers in RedOx reaction to drive ATP synthesis.
In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements:
Statement I: Phosphocreatine is formed from ATP in the resting cell and ATP is low. Phosphocreatine thereby acts as a buffer in the cell that contains creatine kinase.
Statement II: ATP is formed in the cell in mitochondria and chloroplast by a mechanism i.e., essentially ATP driven ion transport operating in reverse.
In the light of the above statements, choose the most appropriate answer from the options given below

pI value of an ionizable 'R'-group of an amino acid residue in a protein may vary from its original value
A. Due to interaction with other ionizable groups present in the surrounding
B. Due to the loss of charge of \(\alpha\)-amino and \(\alpha\)-carboxyl groups of amino acid residue
C. Due to the non-interactive nature of ionizable R - group
D. Due to the presence of ionizable R - group in peptide backbone
Choose the correct answer from the option given below:

Given below are two statements:
Statement I: Hydrolysis of a peptide bond takes place rapidly because the activation energy of peptide bond hydrolysis is high
Statement II: Hydrolysis of the peptide bond is an exergonic reaction

Given below are two statements:
Statement I: If pH of a protein solution is more than its pI then the number of negatively charged protein molecules is more than the positively charged protein molecules
