Given below are two statements:
Statement I: Alkaptonuria is known as an inborn error of metabolism associated with certain amino acids
Statement II: The mutation of homogentisate 1,2-dioxygenase (HGD) gene leads to abnormal metabolism of certain amino acids like phenylalanine and tyrosine that leads to alkaptonuria
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

Identify correct statements regarding peptide bond formation
A. A peptide bond is produced in a condensation reaction
B. During peptide bond formation, a water molecule is released from the reactant
C. A Peptide bond is a covalent bond
D. A Peptide bond is a non-covalent bond
Choose the correct answer from the option given below:

Given below are two statements:
Statement I: Increase in temperature of a reaction mixture up to an optimum value increases the rate of enzyme reaction as it enhances the rate of collision between the substrate and enzyme active sites
Statement II: Increase in the temperature beyond an optimum value breaks the non-covalent bonds in enzyme first and thereby reaction velocity is decreased
In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements:
Statement I: Enzyme can be regulated allosterically if it has at least one ligand-binding site other than the active site
Statement II: Enzyme can be regulated by phosphorylation and dephosphorylation.
In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements:
Statement I: Suicidal inhibitor causes covalent modification of an enzyme active site and enzyme permanently becomes inactive
Statement II: Covalent modification of enzyme active site is initiated after binding of substrate to the active site of an enzyme - suicidal inhibitor complex
In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements:
Statement I: For the culture of mammalian cell lines, glutamine is added to the culture media that serves as the precursor of nucleic acids besides being an important source of energy.
Statement II: Cholesterol and phospholipids are used in the basal media of several serum-free media formulations
In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements:
