Question

Biomolecules occur in the cellular pool as
A) Solutes in true solution.
B) Colloids in colloidal solution.
C) Insoluble in cellular-structure.
D) All the above.

Answer 1

Hint: Chemicals or molecules present in the living organisms are known as biomolecules. The collection or sum total of various kinds of biomolecules, compounds, and ions present in a cell is called the cellular pool.

Complete answer:
The collection of various types of molecules in a cell is called the Cellular pool. Chemicals of the cellular pool are acquired from outside. The cellular pool contains two phases, they are aqueous phase and the non-aqueous phase. The aqueous phase contains chemicals dispersed in water forming either true solution (homogeneous) or colloidal solution (heterogeneous). Substances, which form a true solution are called crystalloids.
The non-aqueous phase contains chemicals deposited in various structures like chromatin, cell membrane, and cell wall. The chemical analysis of living and non-living matter, disclose that both are made up of the same types of elements.
Cellular pool possesses all solutes, colloids, cellular, noncellular structures, etc.
The chemicals of the cellular pool function as raw materials for carrying out several types of biochemical reactions of the cell organelles and the cell. Depending upon their molecular weight and solubility they are divided into two categories: micromolecules and macromolecules.

The correct answer is the option ‘D’ – all the above.

Note:
Chemicals of the cellular pool are acquired from the outer side. The cells are competent to maintain their specific cellular pool by the selective intake of materials from the outer side, their inner metabolism of the cell, and selective elimination of specific chemicals. This is done by the membranous covering of cell organelles and the plasma membrane. The membranes get selective permeability and retentivity.
