In secondary active transport, the sodium iodide transporter moves iodide into the thyroid gland from the...
In secondary active transport, the sodium iodide transporter moves iodide into the thyroid gland from the blood plasma. It cotransports one I- for every two Na+ ions. In mammals, this protein is found predominantly in the thyroid gland, but also in salivary glands, kidneys, gastric mucose, ovaries, and, importantly, in mammary glands, where it is responsible for uptake of iodide into milk, delivering this important element needed to make thyroid hormones. The point of this process is the ACTIVE transport of iodide. Where...
