Halobacterium Lab Investigation Mason Pirio 12/12/13 Period 5 Table Group 3 PS 2- Experiment Design PS 3- Conclusion Writing PS 13- Nitrogen Cycle Abstract- In this experiment we tested to see how well halobacterium grows in different levels of salinity. We found out that the higher salinity in the growth medium the better the halobacterium grows. Background Information- Halobacterium is a bacteria that is found in the great salt lake. Halobacterium is an extremeophile which means it thrives

Effects of Temperature on the Formation of Cheese Curds This lab was performed in order to find what temperature the enzyme chymosin is most effective at forming cheese curds. An enzyme is a protein that acts as a catalyst to speed up biological reactions in cells. They work by lowering the activation energy and help to orient the molecules correctly. Chymosin was originally taken from the stomachs of calves‚ and was called rennet‚ and then purified to make rennin. Eventually to catch up with

Osmosis Rates in Artificial Cells Daniel George Department of Biology Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 georged@mail.gvsu.edu Abstract The lab for this paper was conducted for the topic of osmosis‚ the movement of water from high to low concentration. Five artificial cells were created‚ each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic‚ hypotonic‚ or isotonic solutions for a period of 90

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

The underlining purpose of the experiment was to show that error is ok as long as you know what the flaws are and be able to explain they happened. The lab involved burning a Marshmallow‚ a CHEEZ-IT‚ a Cheeto‚ and A Chex. The heat from the burning snack food is then carried into the H2O and used to calculate the energy content. An improvement that could be made was a replacement for the paperclip; it was

Effects of Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme

kinetics: first‚ we constructed a standard curve for Ortho- Nitrophenyl (ONP)‚ by plotting the absorbance vs number of moles in the standard samples. Then‚ we used our ONP standard curve to determine the amount of product formed in moles. Third‚ using Lineweaver -Burk plot‚ we measured Km and Vmax for our lactase tablet (Diary Relief 9000 FCC). We expected that as the substrate concentration increases‚ the reaction rate will increase until the substrate is large enough and the enzyme is saturated

The primary purpose of this study was to determine whether the Stroop phenomenon is equally strong in both brain hemispheres. Participants collected from our research methods lab were asked to complete an online experiment measuring the time of interference it took them to depict the color of the ink of the color-words. Furthermore‚ each color was assigned a number. For example‚ the ink color red was represented by the number
