Question

5). Enzymes speed up biological reactions by A. Raise the energy of its substrate(s) wer the energy of the products Lower the energy of the transition state D. Binding the substrates E. All of the above 6). 'apoenzyme' is A. ynonymous to coenzyme The part of an enzyme composed of polypeptide chains An active enzyme with all parts for its function except for the subsrate None of the above D. E. 7). Which of the following could be called a "coenzyme' A small protein A complex biomolecule A metal ion A prosthetie ofecule that covalently conjugated to the enzyme A. B. C. Km, the initial rate (Vol of an enzymatic reaction will be A, 33.3% of th C. D. E. 10%. 300%

Explanation / Answer

5)B is the answer

enzyme does not lower the enegry of product and reactants.

It only lowers the energy of transistion.

6)B

APOENZYME is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor.

7)D

Prosthetic groups are non-peptide (non-protein) compounds that mostly attach to proteins and assist them in different ways. They can be inorganic (like metals) or organic (carbon-containing) and bind tightly to their target. Prosthetic groups can bind via covalent (electron-sharing) or non-covalent bonds.
