B. Glycogen, Amino acids, Minerals and Nucleotides.
C. Water, Minerals, Nucleic acids, Amino acids and Nucleotides.
D. Sugars, Water, Minerals, Protein and Nucleotides.

Answer 1

Hint: The cells of the living organism are made up of different types of molecules. The molecules of the cells are the building units of the cell. The cellular molecules such as carbohydrates, minerals etc. are important for many biological processes.

Complete answer:
The environment as well as the structure of the cell are made up of molecules. Cells contain various types of molecules and the interaction between the different types of cells are important for the proper functioning of the cell. The cellular molecules are also involved in the different processes that are necessary to maintain the cell. The molecules join to form more complex compounds.
The molecules of a cell can be divided on the basis of various properties. When they are classified on the basis of their weight and structure, they are of two important types which are macromolecules and micro molecules. The macromolecules are large molecules and are about more than thousand Daltons in molecular weight. They are relatively higher in terms of molecular weight. The important macromolecules are protein, nucleic acids etc. They are actually formed by repetitive smaller molecules which are known as the micromolecules.
The micromolecules are relatively smaller in size and low molecular weight with less than one thousand Daltons. The micromolecules are the monomers which join by bonds to form the polymers or the large molecules. The most important micromolecules are water, amino acids, sugars such as glucose. Minerals are also micromolecules. The micromolecules can occur free as water or may join in a chain like structure to form larger molecules such as amino acid, sugars, nucleotides, lipids and fatty acids.
Water is one of the most important micromolecules. Amino acids are the micromolecules that join to form proteins by peptide bonds. Sugars such as glucose are simple molecules. The nucleotides are the micromolecules that form the nucleic acids. The micromolecules act as substrates for various reactions and are also the products of metabolism. The micromolecules are joined together to form the macromolecules. The micromolecules are linked in different combinations to give rise to complex polymers or macromolecules.

Therefore, the correct option is option A.

Note: The molecules in a cell are of two types namely micromolecules and macromolecules. The micromolecules are simple, low weight molecules which are joined to form the complex structures of large molecules known as the macromolecules. The important micromolecules of the cell are water, amino acids, sugars and minerals.
