Explanation / Answer
1. Yes, iodine molecule does diffuse across the membrane.
2. Iodine is non-polar and holds negative charge and also the ion gated channels(sodium/iodide symporter) helps in diffusion. When it comes to size iodine atom is huge and therefore its charge ratio is negligibly affected by any extra electron, but they are small enough to pass through the membrane.
3. No, starch molecules does not diffuse across the membrane.
4. Starch molecules does not diffuse across the membrane because it is too complex and large to pass through a membrane.
