Effectors may show stimulatory or inhibitory activity. Binding one subunit impacts binding of substrate to other subunits. ALL are correct. The enzyme can have multiple subunits. The regulatory effect is by altering conformation and interaction of subunits.

Hello your question is poorly written below is the well written question

All are characteristic of allosteric enzymes except:

a. effectors may show stimulatory or inhibitory activity

b. they have multiple subunits

c. they obey Michaels-Menten kinetics

d. the regulatory effect is by altering conformation and interation of subunits

e. binding one subunit impacts binding of substrate to other units.

Answer : They Obey Michaels-Menten kinetics ( c )

Explanation:

Allosteric enzymes are enzymes that posses the presence of an additional site and an active site.  they are modified by a noncovalent binding an allosteric effector. They do not posses a kmvalue hence they do not obey Michaels-Menten kinetics

c

explanation:
