|
The researcher should measure the temperature during the reaction.

Detailed explanation-1: -A researcher wants to determine the effectiveness of an enzyme at various temperatures. Which of the following would best help the researcher determine how well the enzyme is working? The researcher should measure the rate of the reaction.
Detailed explanation-2: -As the temperature increases so does the rate of enzyme activity. An optimum activity is reached at the enzyme’s optimum temperature. A continued increase in temperature results in a sharp decrease in activity as the enzyme’s active site changes shape.
Detailed explanation-3: -The temperature at which the rate is fastest is called the optimum temperature for that enzyme. Different enzymes have different optimum temperatures. Some enzymes, for example, in organisms known as thermophiles or extremophiles are capable of working at temperatures like 80°C or even higher.
Detailed explanation-4: -The optimum temperature is the temperature at which the enzyme functions best.
