How was the highest temperature we measured different from the lowest temperature we measured?Group of answer choicesIt had a slower reaction rate.It had a faster reaction rate.There was no difference in reaction rates.The enzyme above 50°C did not work at all.

An enzyme-catalyzed reaction proceeds 40 times faster at 25 °C than at 4 °C.Estimate the overall activation energy for the process responsible for thisreaction.

Which of these temperatures will allow faster enzyme substrate complex formation?*0403020

(c) The student repeats the experiment on a different day, using 25 cm 3of potassium hydroxide solution and 25 cm 3of dilute hydrochloric acid.The thermometer shows the highest temperature reached at the end of the experiment. °C 25 20(i) Complete the table by giving the missing information.Give both temperatures to the nearest 0.1 °C. (2) mean temperature at start in °C temperature at end in °C temperature rise in °C5.2

How will each of the following changes in conditions alter the rate of an enzyme-catalyzed reaction? Select the single best answer for each part.Part 1 of 2Increasing the temperature from 37°C to 100°CNo effect on the rate of reactionIncreases the rate of reactionDecreases the rate of reaction until the reaction stops

Explain how increasing the temperature can cause an enzyme to denature.
