Molecular Mechanisms of Voltage Gated Ion Channels

Voltage-Gated Ion channel, a protein expressed by virtually all living cells that create a pathway for charged ions from dissolved salts, including sodium, potassium, calcium, and chloride ions, to pass through the lipid cell membrane that would otherwise be raincoat. The function of the cells of the nervous system, the contraction of the heart and … Read more

Thyroid Hormone

Thyroid hormones Your thyroid makes 2 main hormones: triiodothyronine (T3) and thyroxine (T4). Adequate amounts of iodine (a chemical element that is an essential part of our diet) are needed for the thyroid to produce these hormones. Another hormone that is produced in the thyroid gland is called calcitonin. This hormone, secreted by a small … Read more

Active Transport (Sodium-Potassium Pump)

Active Transport: The Sodium-Potassium Pump Since the plasma membrane of the neuron is highly permeable to K+ and slightly permeable to Na+, and since neither of these ions is in a state of equilibrium (Na+ is found in a higher concentration outside the cell than inside, and K+ in higher concentration inside the cell), then … Read more
