Calcium Homeostasis: Regulation & Maintenance

Regulation

Extracellular calcium is transported throughout the body via the blood vessels. Two primary factors are responsible for stabilizing blood calcium levels: the parathyroid hormone, in short PTH, which forms in the parathyroid glands, and vitamin D, which is synthesized in the liver and skin and converted into its active form, calcitriol, in the kidney. A third regulator is calcitonin, which forms in the thyroid gland. An interactive version of this Chalk Talk episode can be found at: […]

Prokaryotic Gene Regulation: Lac Operon

Regulation

The first fully described genetic regulatory mechanism is the lac operon in E. coli bacteria. Today, it still represents an adequate model for prokaryotic gene regulation. An operon is a transcription unit of genes whose products are required under identical circumstances. So, it facilitates the coordinated expression of multiple genes.
