Answer 1

Answer:

more than 30 seconds

Explanation:

theres some extra

question : To study the actions of the enzyme catalase on hydrogen peroxide, students performed the following experiment. Catalase was extracted from potatoes and stored on ice. The following hydrogen peroxide solutions were made: 1%, 5%, 10%, 15%. Filter paper disks were soaked in the catalase then dropped into each of the solutions. Enzyme activity was measured by the time it took for the disks to float from the bubbles produced. Here is the data:

Which of the following best describes why the disks float faster to the surface in more concentrated solutions?

asnwer

the higher substrate concentrations in the more concentrated solutions speeded up the reaction
