Concept explainers
(a)
Interpretation:
Whether the statement, “The active site of an enzyme is the portion of the enzyme in which the catalytic properties occur” is true or false is to be stated. If false, the correct statement is to be stated.
Concept introduction:
Enzymes are organic molecules present in the cells which catalyze biochemical reactions. They speed up the
(b)
Interpretation:
Whether the statement, “The induced fit model explains why one enzyme helps many reactions to occur faster” is true or false is to be stated. If false, the statement is to be re-written.
Concept introduction:
Enzymes are organic molecules present in the cells which catalyze biochemical reactions. They speed up the rate of the reaction and remain intact at the end of the reaction. All biochemical reactions in living cells require enzymes to proceed.
(c)
Interpretation:
Whether the statement, “An enzyme substrate is the material that is the product of the enzyme-catalyzed reaction” is true or false is to be stated. If false, the statement is to be re-written.
Concept introduction:
Enzymes are organic molecules present in the cells which catalyze biochemical reactions. They speed up the rate of the reaction and remain intact at the end of the reaction. All biochemical reactions in living cells require enzymes to proceed.
(d)
Interpretation:
Whether the statement, “An irreversible enzyme inhibitor cannot be removed from the enzyme’s active site” is true or false is to be stated. If false, the statement is to be re-written.
Concept introduction:
Enzymes are organic molecules present in the cells which catalyze biochemical reactions. They speed up the rate of the reaction and remain intact at the end of the reaction. All biochemical reactions in living cells require enzymes to proceed.
