Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration

sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the bacteria over hand sanitizer and hand soap. Methods I planned my experiment to test the effects of topical chemicals on bacteria living on my hands. In doing

The investigation into the effect of social facilitation on the performance level within the Stroop effect. Abstract The relationship between social facilitation (first discovered by Triplett in 1898) and the issue of interference within the Stroop effect were investigated. Fifty participants were recruited and took part in a repeated measures design. Participants were given a list of congruent and incongruent words in single and paired situations. The overall findings of this study suggest

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

How healthy are chocolate chip cookies? I started out researching on how to bake cookies‚ however‚ while I was researching I decided to change my topic on how baking gluten free cookies are healthier compared to normal cookies. This past winter my sister was diagnosed with Rheumatoid Arthritis‚ causing her to become gluten free. My mom has been making gluten free chocolate chip cookies for her so she can still enjoy cookies. First‚ I went to Google still thinking about how to bake cookies and found

purpose of this experiment was to test different solute concentrations on the rate of osmosis. Artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area. The weights of the cells were recorded each interval‚ and then the rate of osmosis was found by calculating the corrected cumulative change in weight. The prediction

A chocolate chip cookie is a drop cookie that was originally from the United States and features chocolate chips as its main ingredient. The traditional recipe contains a dough composed of butter and both brown and white sugar with semi-sweet chocolate chips. Variations include recipes with other types of chocolate or additional ingredients‚ such as nuts or oatmeal. The chocolate chip cookie was accidentally developed by Ruth Graves Wakefield in 1930. She owned the Toll House Inn‚ in Whitman‚
