the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient‚ (2) To explain experimental data concerning different concentration gradients‚ (3) To complete a data table and prepare a graph to illustrate the data‚ and (4) To apply information from this experiment to other related problems. MATERIALS: 6 pieces of dialysis tubing Sucrose solution concentrations of 0M‚ .2M‚ .4M‚ .6M‚ .8M‚ 1.0M String

Fermentation Lab Introduction For bacteria and many single-celled protists fermentation is a common anaerobic pathway that the cells use to collect energy from carbohydrates to form ATP. The process for fermentation begins in the cytoplasm with a process called glycolysis‚ which converts one molecule of glucose into two molecules of pyruvate. When glycolysis is complete four ATP would be produced but the net yield would be two ATP taking into account the initial investment of two ATP

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any

CASSAVA STARCH AS A MAJOR COMPONENT IN MAKING BIODEGRADABLE PLASTIC ABSTRACT The purpose of this experiment is to be able to help the society with its environmental issues by creating biodegradable plastic out of cassava starch. The procedures that the researchers used in this investigatory project were all experimental and were based on Scientific Method. The researchers used environment-friendly materials which can be made into biodegradable plastics that will not harm the environment

Gram Negative Unknown Lab Report Abstract The Unknown Gram Negative bacterium inoculated in a Tryptic Soy broth medium was randomly selected from a group of other unknowns. In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

If the glucose and starch solution stays within the beaker of water for a longer period of time‚ then more water will travel through the selectively permeable membrane due to the effects of diffusion on the solution. If the level of sucrose within the solution increases‚ then the effects of osmosis will cause the change in mass to also increase due to higher concentrations of sucrose and the increased net movement of the water molecules within the solution. Analysis - When the glucose and starch

soluble in lipids‚ but not in water. Benedict’s solution is the test used for reducing sugars or glucose testing. The positive reaction for this test should show a red/brick color after being placed in boiling water for three minutes‚ but if a negative reaction occurs we will get blue color or no change at all. Another test that we were introduced to was the iodine test‚ which is used to detect starch. A positive reaction would result in a blue/black color‚ where as a negative reaction would be
