Magnesium is absorbed in the small intestine through diffusion and ____.

Question

Quizplus · Accepted Answer

Magnesium is primarily absorbed through carrier-mediated active transport in the small intestine. This is because the concentration gradient of magnesium is typically lower in the lumen of the small intestine than in the enterocyte, so active transport is necessary to move it against the concentration gradient. Diffusion and facilitated diffusion may also play a minor role in magnesium absorption, but they are not the primary mechanisms. Osmosis and peristalsis are not involved in the absorption of magnesium.
