Question

Quizplus · Accepted Answer

Chloride ions (Cl-) are primarily absorbed in the small intestine through secondary active transport and passive diffusion, particularly paracellularly, rather than through primary active transport. Secondary active transport often involves the movement of Cl- ions in conjunction with other ions, such as sodium (Na+), where the energy derived from the transport of one ion down its concentration gradient is used to transport another ion against its gradient. Passive diffusion allows Cl- ions to move between cells (paracellular route) down their concentration gradient. Primary active transport, which directly uses ATP to transport ions against their concentration gradient, is not a major mechanism for Cl- absorption in the small intestine.
