Starch is digested by the enzyme amylase.
A student did an investigation on amylase activity.
This is the method used.
1. Mix amylase solution and starch suspension at 20 °C in a boiling tube.
2. Remove a drop of the mixture every 30 seconds and test it for starch.
3. Continue testing every 30 seconds until no starch is detected.
4. Repeat the investigation at different temperatures.

Answer:

An incubator.

Explanation:

Most enzymes work best at about 37 °C and start to denature around 40 °C.

Thus, the student should use a laboratory incubator, which is essentially an oven that can heat a biological sample to a set temperature.

This model shown below reaches a maximum temperature of 62° C, and its heat controller maintains temperatures within ± 0.5 °C°.

The student should use an incubator to control the temperature of the mixture.

INCUBATOR:

  • An incubator is an experimental device used to provide controlled environmental conditions such as temperature, humidity etc.

  • According to this question, a student is investigating the activity of amylase enzyme at different temperatures.

  • The temperature of the mixture made from starch suspension and amylase solution can be controlled at desired temperature using an incubator in the laboratory.

  • Therefore, the student should use an incubator to control the temperature of the mixture.
