[2025-10-01T02:22:57.794471] [PI reasoning] **Finding iron transporter info**

I need to address a multiple-choice question about iron entry into enterocytes, specifically asking about the transporter involved. The correct answer is A, as Divalent Metal Transporter-1 (DMT1) mediates iron uptake from the intestinal lumen. It’s a straightforward question, but I’ll still include citations for support. I'll quickly find relevant articles to back up the information about DMT1's role in iron uptake. This ensures a solid answer!
