Examine the picture below, which shows the inhibition of an enzyme. Does this mcchunwmi indicate the presence of compelling inhibition oc noncompruuve inhihitior a. Competitive b. Noncompetitive c. Neither type is shown d. Not enough information is given to make a determination In which type of inhibition is it possible to restore the maximum rate of enzyme activity by adding additional substrate? a. cooperative inhibition b. competitive inhibition c. noncompetitive inhibition d. selective inhibition what is the formula of the neutral compound formed by an iron(III) ion and oxygen? a. FeO b. FeO_2 c. Fe_2O_3 d. Fe_3O_2

Explanation / Answer

1) The given mechanism indicates the presence of competitive inhibition.
In competitive inhibition an inhibitor competes with the substrate for the active site of an enzyme. While the inhibitor occupies the active site it prevents the binding of substrate to the enzyme.
In mechanism that’s only shown.
Answer: a) competitive.
========================XXXXXXXXXXXX=====================
2) In competitive inhibition inhibitor binds reversibly to the enzyme. Hence the competition can be biased to favor the substrate simply by adding more substrate.
Answer: a) competitive inhibition.

3)
Oxygen shows stable -2 O.S. in its metal oxides.
a) In FeO
As O is in -2 oxidation state, Fe will have +2 O.S. and not +3.
2) In FeO2
Fe would have +4 O.S.
3) In Fe2O3
3 O makes total of –2 x 3 = –6 O.S.
Hence 2 Fe will have total of +6 O.S. and hence Fe will be in +3 i.e. Fe(III) form.
Answer: c) Fe2O3
d) In Fe3O2
2 O makes it -4
And hence 3 Fe would be +4 i.e. Fe would be +4/3 hence rulled out.
