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.

reversible	the enzyme has cooperative binding of              substrate
amplification can occur	only activation occurs
requires a kinase	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.

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.

irreversible	the enzyme has Michaelis-Menton kinetics
no amplification can occur	either inhibition or activation can occur
requires a phosphatase	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.

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.

requires a protease	either inhibition or activation can occur
requires a phosphatase	an inactive proenzyme → an active enzyme
reversible	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.

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.

amplification can occur	an enzyme-modulator complex is formed
requires a kinase	the rregulated enzyme has quaternary structure
irreversible	no additional enzyme is required
