Answer 11

Proteins

Question 12

In proteins, it is the molecules that are necessary in small quantities to allow a biochemical reaction to continue even though they do not directly enter into the reaction

Answer 12

Enzymes

Question 19

In molecular composition, it is located principally in the nucleus of the cell acid or RNA.

Answer 19

Nucleic Acid

Question 20

Two types of Nucleic Acid:

Answer 20

Deoxyribonucleic Acid (DNA) and Ribonucleic Acid

Question 21

In nucleic acid, this serves as the command or control molecule for cell function.

It is the radiation-sensitive target molecule.

Answer 21

Deoxyribonucleic Acid

Question 22

In nucleic acid, it is located in the cytoplasm and it forms in the nucleus.

It has messenger and transfer.

These molecules are involved in the growth and development of the cell through a number of biochemical pathways such as protein synthesis.
