regulation proteins

Responsible for muscle contraction for movement and locomotion Example : Myosin Harmones Some harmones are proteins. Harmones regulate body functions Example : Insulin Structural Proteins form parts of cells and tissues Example : Collagen Protective ..

It controls the operator gene in cooperation with a substance called co repressor present in the cytoplasm. The regulator gene codes for a protein named aporepressor. The latter combines with the co-repressor, and aporepressor-co-repressor complex joins the operator gene, which ..

Proteins - Introduction - Proteins are the high molecular mass complex biopolymers of amino acids and organic compounds that are most important to life. They are essential for growth and maintenance of life. They are high molecular weight, nitrogen rich substances that are prese..

Introduction - Genes do not operate to produce enzymes all the time. Each gene is normally more or less repressed (inactive); but, when a particular enzyme is needed, the relevant gene becomes active to bring about the production of that enzyme. A totally active gene can produce a very large amount..

Gene Regulation in Eukaryotes - In eukaryotes, the genes that code for the enzymes needed to catalyse the various steps of a particular metabolic pathway may not be adjacent or even be in different chromosomes. However, these genes are regulated by operon model as in bacteria. B..

An operon is the unit of transcription. When excess protein is present, it is no longer economical for the cell to use up its energy and materials in the synthesis of enzymes that are not immediately needed. Hence, the protein synthesis is stopped. This is clearly advantageous f..

Hormones are informational molecules. They are secreted in response to changes in the environment inside or outside the body. These are released into the extracellular fluid, where they are diffused into the blood stream. The latter carries them from the site of production to the site of action. Th..

and minerals are responsible for regulating and coordinating the various activities of an organism along with enzymes (proteins..
