Final answer:
Sensors to be attached to the Labquest for the described experiment include a temperature sensor, a pH sensor, and a conductivity sensor, which measure temperature, pH, and conductivity respectively.
Step-by-step explanation:
The sensors to be attached to the Labquest for this experiment are: a temperature sensor, a pH sensor, and a conductivity sensor.
These instruments are essential for measuring and recording data such as temperature, pH, and conductivity which are important variables in many scientific investigations, including those exploring enzyme activity.
A temperature sensor measures the temperature before and after changes in a system, a pH meter is used to determine the pH value of a solution by measuring the potential across its glass electrode, and a conductivity meter measures the ability of a solution to conduct electric current.
For instance, in biochemical experiments, the rate of an enzymatic reaction can be affected by changes in temperature and pH levels. Figure 19.5.2 illustrates the effects of these variables on enzyme-catalyzed reactions. Proper use of a pH meter is crucial, with the glass bulb on the electrode being fragile and requiring careful handling.
