BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The proteome is the entire set of proteins that is, or can be, expressed by a genome, cell, tissue, or organism at a certain time. It is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions. Proteomics is the study of the proteome.

Detailed explanation-2: -(PROH-tee-ome) 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: -Even though all cells of a multicellular organism have the same set of genes, the set of proteins produced in different tissues is different and dependent on gene expression. Thus, the genome is constant, but the proteome varies and is dynamic within an organism.

Detailed explanation-4: -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-5: -Mass spectrometry-based methods, affinity proteomics, and micro arrays are the most common technologies for large-scale study of proteins.
