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:

Dialysis bags are semi - permeable membranes. Small molecules like glucose can pass through due to their size, while large molecules like starch cannot as they are too big to fit through the pores of the membrane.

Answer:

No, starch cannot pass through the dialysis bag because it is a large molecule. Glucose can move through the bag because it is a small molecule.
