Placental GLUT1 Kinetics — 2D Saturation & Flow Diagram

Glucose is the fetus's principal fuel, and every molecule that reaches it must first cross the syncytiotrophoblast via GLUT1, a facilitated-diffusion carrier that follows symmetric Michaelis-Menten kinetics rather than simple concentration-driven diffusion. This 2D companion view drops the 3D particle chamber and instead plots the transport mathematics directly: a live saturation curve, a two-compartment tank/flow schematic, and a scrolling strip chart of flux and fetal glucose over time — the same equation, read three different 2D-native ways. Adjust maternal glucose, GLUT1 density and membrane thickness and watch all three views respond together, including the saturation ceiling that keeps fetal glucose delivery from scaling linearly with maternal hyperglycemia.
