Movement of water across membranes that does NOT require cellular energy 2. Hypertonic solutions contain high concentration of solute when compared to another solution. 3. When a cell is placed in a hypertonic solution‚ what happens to the cell? shrivels 4. Play the small movie. 5. Hypotonic solutions contains a low concentration of solute when compared to another solution. 6. When a cell is placed in a hypotonic solution‚ what happens to the cell? swells 7. Play the small movie.

in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If the solutions differ in concentration‚ the area with the higher solute concentration is hypertonic and the area with the lower solute concentration is hypotonic. Besides osmosis and diffusion‚ molecules and ions can be moved by active transport. This process includes the use of ATP (adenosine tri-phosphate) to drive

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced (isotonic). In order for osmosis to occur naturally‚ a semi-permeable membrane is required as a medium. A visking tubing is a semi-permeable membrane‚ therefore it will be used to act as the ‘cell’ for the experiment. This is because the phospholipid bilayer

Throughout time many athletic players drink sport drinks like gatorade or powerade but the question is when should we drink sport drinks or water. Your body needs water to maintain performance. Water is composed of two hydrogen and one oxygen atom. For your body to maintain athletic performance it must have oxygen in the muscles (which water contains). When exercising we burn carbohydrates. When we lose these carbohydrates they need to be replaced. There are many alternatives to replace carbohydrates

cell reaction to an isotonic‚ hypotonic‚ or hypertonic solution. Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective was to properly use a pipette (Spilios‚ 2015). Hemolysis occurred despite the red blood cells being in isotonic solution (0.3 M)

A hypotonic solution would have a high water potential and a low solute potential. An isotonic solution would have equal solute and water potentials. Water

sample is dark and smaller. Result : 1) RBC’S when placed in distant water solution with a lower concentration level hypotonic the cell will swell and burst . 2)RBC’S when placed in a Nacl solution with the same concentration level isotonic the cell will remain the same no change in shape or size . 3)RBC’S when placed in Nacl solution with higher concentration level hypertonic the cell will shrink and

in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic solution is .2 M and 0 M‚ around .4 M the mass stays near the same because it is an isotonic solution‚ lastly the mass decreased when the hypotonic solution is .6 M and above. The experiment was developed with 6 plastic cups containing varying
