to have in the body. A substrate is the material that is being broken down. In this case‚ the substrate would be hydrogen peroxide. The catalase‚ located in the liver‚ is being used to break down the substrate. Problem The purpose of this lab is to see if the enzyme‚ catalase‚ can be manipulated. We are testing the effects of pH‚ temperature and enzyme concentration. Hypothesis Controlled When we add peroxide to the liver it will bubble a lot and break down faster. When we add peroxide

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from
