BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A proteome is the complete set of proteins expressed by an organism. The term can also be used to describe the assortment of proteins produced at a specific time in a particular cell or tissue type. The proteome is an expression of an organism’s genome.

Detailed explanation-2: -The complete set of proteins made by an organism. Proteins are made in different amounts and at different times, depending on how they work, when they are needed, and how they interact with other proteins inside cells.

Detailed explanation-3: -The proteome is defined as the expressed protein complement of a cell, organ, or organism and it includes all isoform and posttranslational variants.

Detailed explanation-4: -The proteome is defined as the entire set of proteins in cells, tissues or organisms.

Detailed explanation-5: -Thanks to the human genome project, we can now estimate the number of protein-coding genes to be in the range of 19, 587–20, 245 (refs. 1, 3, 4). Thus, if a single representative protein from every gene is used as the definition of the proteome, the estimated size is just  20, 000.
