Question

Which of the following types of reactions account for the synthesis of macromolecules?

Select one:

a. Hydrolysis reactions

b. Condensation reactions

c. Group transfer reactions

d. Redox reactions

Why are macromolecules continually being synthesized in a cell?

Select one:

a. Macromolecules typically have a half-life in the order of days.

b. If the energy produced by the cell through aerobic respiration is not used, components of the cell will become oxidized.

c. Growth of the cell requires the synthesis of new components.

d. a and c.

e. b and c.

Explanation / Answer

1. Hydrolysis Reaction. option A.

For the synthesis of macromolecules the monomers are joined together to form a polymer where losing of water takes place due to dehydration the macromolecules are formed. Loss of water is called hydrolysis reaction.

2. option E. both a and c.

(B) If some of the energy is produced by the aerobic reaction when that enery is not used the cell will become oxidized oxidation is the process of removal of hydrogen i.e water. as i mentioned above when water is losed macromolecules is synthesised.

(C) yes of course the cell requires synthesis of new components for the growth.

so both the options are correct.

Answer is Option E.
