Potato Enzyme Lab Report

A enzyme is a catalyst made of protein and it’s purpose is to expedite the period of a reaction. Enzymes are commonly large and have a surface that is purposed with grabbing other molecules, their surfaces contain hydrophilic amino acids which result in the enzymes being soluble in water. The 3D structure of an enzyme allows a substrate to connect to it’s active site and this allows product to be formed from their binding. As the substrate and enzyme bind, the substrate changes it’s shape and that discontinues product being formed. Enzymes have a tertiary structure and genes that came from DNA were reproduced in proteins (including enzymes).
My experiment decides to test: How does temperature affect the activity of an enzyme? Next, as my hypothesis: “If a enzyme is heated, then the reaction rate will be quicker and there will be more product.” In order to conduct an experiment I have to set up my materials, I will need: 1 potato, hydrogen peroxide, knife, hot plate, timer/clock, three cups, and a beaker. For my procedure,
Divide the potato into three even sections with the knife.
Put one third of the potato in the freezer for 45 minutes.
After 45 minutes take the potato out.
Mash the frozen potato and take out a small fragment.
Place the fragment into a cup and submerge
Both the frozen and hot potato reacted with fewer bubbles and at slower rate, the catalyst did not react in favor of the change in temperature and slowed down the rate of the reaction and produced less product. The piece of the potato kept at room temperature produced many bubbles over a longer period of time. When the enzyme Catalase is altered from its original temperature, it's more unstable and unable to produce as much product in a shorter amount of
