Q

How will you be able to determine the amount of product that is produced at each time period?

A

When the artifical substrate reaction turns yellow once the base is added, you can tell how much product is produced. The deeper the color, the higher the amount of product is made. You can:

  • Compare the yellowness of enzyme reaction samples to a set of known standards
  • Use a spectrophotometer
