Based on the data provided, we can analyze the observations regarding amylase and starch:
- Starch: 3 - Indicates the presence of starch.
- Amylase: 2 - Indicates amylase is present.
- Temp: 35 - This is a suitable temperature for enzyme activity.
- Maltose: 0 - No maltose is present, which suggests that amylase did not break down starch into maltose.
- Maltase: 0 - No maltase is present, which is not directly relevant to the reaction with starch but indicates that maltase isn't being produced or isn't in the reaction mixture.
- pH: 7 - A neutral pH that is generally suitable for enzyme activity.
- Glucose: 0 - Indicates that no glucose has been produced.
Now we evaluate the options based on this information:
a. Amylase did not have a reaction with starch - This appears to be true based on the fact that there is no maltose (0) or glucose (0) produced.
b. Amylase reactive starts to create glucose molecules - This is false as no glucose is produced.
c. Amylase reacted with starch to create Maltose molecules - This is also false as there is no maltose produced (0).
Therefore, the correct observation is:
- a. amylase did not have a reaction with starch.
