*Please use a better topic title.*

No, amylase doesn’t use cellulose as a substrate. Starch is the substrate for amylase. Test Tube #3 should not show a positive Benedict’s test because cellulose is not the substrate for amylase.

2. What about test tube 5? Explain.

The bacteria were able to digest the cellulose because they produce the enzyme, cellulase.
