Question

1. dialysis bag experiments. small molecules pass (water, glucose). large molecules stay (starch, protein). review questions: can starch pass through the dialysis bag? why can glucose move through the bag?

Explanation:

The text states that large molecules like starch stay in the dialysis - bag and small molecules like glucose can pass through. This is due to the semi - permeable nature of the dialysis bag which allows small molecules to diffuse through its pores while preventing the passage of large molecules.

Answer:

1. No, starch cannot pass through the dialysis bag because it is a large molecule.
2. Yes, glucose can move through the bag because it is a small molecule.
3. Glucose can move through the bag because it is a small molecule and the dialysis bag is semi - permeable, allowing small molecules to diffuse across it.
