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: -Each enzyme has a temperature range in which a maximal rate of reaction is achieved. This maximum is known as the temperature optimum of the enzyme. The optimum temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius). There are also enzymes that work well at lower and higher temperatures.
Detailed explanation-4: -The optimum temperature is the temperature at which the enzyme functions best.
Detailed explanation-5: -Hence it is important to have an optimum temperature for the activation of the enzyme. Additional Information:-The optimum temp of enzymes is 20-35°C. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C.
