1-6. Answer with (P) proteolysis; (C) covalent modification; (A) allosteric regulation.
Answer with only one choice even if two are correct. Use each choice at least once.

A, C        reversible	A, C*   the enzyme has cooperative binding of              substrate
C, P       amplification can occur	P         only activation occurs
C       requires a kinase	C         inactive enzyme b → active enzyme a
7-8. Identify the molecules using these choices: (A) adenine; (C) cytosine; (F) fructose; (G) guanine; (R) ribose; (T) thymine; (U) uracil.		9-10. This is not glucose. Circle the carbon with the non-glucose configuration, and write either α or β to indicate which anomer is shown.
F	A

1-6. Answer with (P) proteolysis; (C) covalent modification; (A) allosteric regulation.
Answer with only one choice even if two are correct. Use each choice at least once.

P        irreversible	P        the enzyme has Michaelis-Menton kinetics
A        no amplification can occur	A, C       either inhibition or activation can occur
C       requires a phosphatase	C        active enzyme a → inactive enzyme b
7-8. Identify the molecules using these choices: (A) adenine; (C) cytosine; (F) fructose; (G) guanine; (R) ribose; (T) thymine; (U) uracil.		9-10. This is not glucose. Circle the anomeric carbon, and write the number of the carbon with the non-glucose configuration.
C	R

1-6. Answer with (P) proteolysis; (C) covalent modification; (A) allosteric regulation.
Answer with only one choice even if two are correct. Use each choice at least once.

P       requires a protease	A, C     either inhibition or activation can occur
C       requires a phosphatase	C        an inactive proenzyme → an active enzyme
A, C       reversible	A, C*        the enzyme does not have Michaelis-Menton              kinetics
7-8. Identify the molecules using these choices: (A) adenine; (C) cytosine; (F) fructose; (G) guanine; (R) ribose; (T) thymine; (U) uracil.		9-10. This is not glucose. Draw an arrow to the anomeric carbon and circle the carbon with the non-glucose configuration.
T	F

1-6. Answer with (P) proteolysis; (C) covalent modification; (A) allosteric regulation.
Answer with only one choice even if two are correct. Use each choice at least once.

C, P      amplification can occur	A       an enzyme-modulator complex is formed
C        requires a kinase	A, C*   the regulated enzyme has quaternary structure
P        irreversible	A     no additional enzyme is required
7-8. Identify the molecules using these choices: (A) adenine; (C) cytosine; (F) fructose; (G) guanine; (R) ribose; (T) thymine; (U) uracil.		9-10. This is not glucose. Draw an arrow to the carbon with the non-glucose configuration, and write either α or β to indicate which anomer is shown.
U
