There are six major groups of enzymes. The categories are based on the types of
reactions that they catalyze.
What type of enzyme converts a molecule to another structure with the same
formula through breaking bonds and forming new bonds.
A) Lyases
B) Transferases
C) Hydrolases
D) Isomerases
E) Ligases
Allosteric enzymes:
A)usually catalyze several different reactions within a metabolic pathway.
B)are regulated primarily by covalent modification.
C)usually show strict Michaelis-Menten kinetics.
D)usually have more than one polypeptide chain
E)usually have only one active site.
You are studying a metabolic pathway and are trying to decide if it is an anabolic
pathway or a catabolic pathway. Which of the following would help diagnose this
problem?
A) Look for common intermediates.
B) Look for ATP-requiring steps.
C) Look for enzymes under allosteric regulation.
OD) All of the above.
OE) None of the above.
