Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Grade 12 Biology (SBI 4U1) Nicole Mikulis Unit: Biochemistry Sept 14 2012 Lab: Effect of temperature and pH on catalase activity BACKGROUND Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in

year I became interested in figuring out how the using the same recipes the outcome could be so different. Background Information: Osmosis is the of a solvent across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The water being the solvent can move across the membrane but the salt

This Chip Can Tell If You’ve Been Poisoned Quick detection. This 2-cm-wide chip (inset) can quickly test for botulism‚ a deadly disease caused by theClostridium botulinum bacterium. When you are dealing with a deadly poison that can be found in food and is a potential terrorist weapon‚ you want the best detection tools you can get. Now‚ researchers in France have demonstrated an improved method to detect the most deadly variant of the botulinum neurotoxin‚ which causes botulism. Their test

Experiment: Turgor in Potato Tissue 1. We labelled three test tubes A‚ B‚ C‚ D and added initials of people in our group. 2. Used a syringe or graduated pipette to put 20 cm3water in tube A and 10 cm3 in tube B. 3. Put 20 cm3 of 17% solution in tube C and 10 cm3 in tube B; put 20 cm3 pure sucrose solutions in tube D. 4. Working on the dissecting board I cut the ends off large potato. I was careful with the knife and cut it onto the dissecting board away from myself. 5. Used a cork

OSMOSIS LAB BACKGROUND INFORMATION. Dialysis tubing is being used to model a plasma membrane. Isotonic solutions are solutions that have the same concentration of solutes on both sides of the membrane. Hypertonic solutions are solutions that have more solute to the one with less solute. Hypotonic solution are solutions that have less solute to the one with more solute. RESEARCH QUESTION:which dialysis tubing will gain the distilled water and which one will loss its content
