Question
Chapter 18, Problem 14P
Interpretation Introduction
Interpretation:
Iron acts as an electron carrier in a coupled
Concept introduction:
The redox potential is the measure of the tendency of any chemical compound to lose or accept electrons and attain an oxidized or reduced state. The electrode potential of a compound to accept an electron is termed as reduction potential. Further, the oxidation potential is the potential of the compound on losing its electrons

The number 2 question. Thank you
Enzymes catalyze chemical reactions. What constitutes the active site of an enzyme? What are the turnover number (kcat), the Michaelis constant (Km), and the maximal velocity (Vmax) of an enzyme? The kcat (catalytic rate constant) for carbonic anhydrase is 5 × 105 molecules per second. This is a “rate constant,” but not a “rate.” What is the difference? By what oncentration would you multiply this rate constant in order to determine an actual rate of prod- uct formation (V)? Under what circumstances would this rate become equal to the maximal velocity (Vmax) of the enzyme?

X shows a fairly sharp decrease in its activity when the pH goes much lower than 5.8. One likely interpretation of this pH activity is that: a Glu residue on the enzyme is involved in the reaction. a Tyr residue on the enzyme is involved in the reaction. a His residue on the enzyme is involved in the reaction the enzyme uses NADH has a cofactor. the enzyme uses coenzyme A has a cofactor.arrow_forward
