foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity. With the increased level of damage to the potato‚ there appeared to be more activity within the reaction between the catalase and the H2O2. b) Explain at the cell level why crushing or macerating the potato has this effect. When you crush or macerate the potato‚ you are breaking the cell walls of each individual cell. Once this happens‚ the catalase is

in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement of water into the potato pieces. Therefore

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel down its concentration gradient‚ which was from a higher concentration (in the cell) to a lower concentration (in the solution)‚ which meant the potato cells lost water‚
