Question

True or False:

Explain why False statements are not True.

1. NAD+ can be reduced by two electrons to NADH, with both electron carried on the adenine ring of the dinucleotide.

2. The rate of a chemical reaction is proportional to the number of molecules having the transition state free energy.

3. Accurate kinetic constants are easily obtained from a V vs S plot of an enzyme displaying Michaelis - Menten Kinetics.

4. The catalytic triad in chymotrypsin is responsible for both positioning the substrate and hydrolyzing the substrate peptide bond.

5. Hexokinase from brain tissue is more active than hexokinase from the liver due to its lower Km.

1) NAD+ can be reduced by two electrons to NADH, with both electron carried on the adenine ring of the dinucleotide.

Ans- True

2) The rate of a chemical reaction is proportional to the number of molecules having the transition state free energy.

Ans- False- According to law of mass action rate of a chemical reaction is proportional to the product of molar concentration of the reactant.

3) Accurate kinetic constants are easily obtained from a V vs S plot of an enzyme displaying Michaelis - Menten Kinetics.

Ans- True

4) The catalytic triad in chymotrypsin is responsible for both positioning the substrate and hydrolyzing the substrate peptide bond.

Ans- True

5) Hexokinase from brain tissue is more active than hexokinase from the liver due to its lower Km

Ans- True
