The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific time intervals to measure the rate of diffusion of water in each different solution. The results illustrated that increased concentration gradient

that takes no energy‚ and that osmosis is just the flow of water through the cell membrane. The main purpose of the first experiment was to examine the movement of H2O and other materials in living and simulate systems. This was done through the dialysis tubing to mimic the cell membrane and measure the change of mass inside the tube filled with distilled water. The quantity of mass before and after was measured and saw the amount gained from the outside environment (either saline‚ sucrose‚ or water)

Treatment should include restoration of the blood volume to normal‚ restricted fluid intake‚ and dialysis. * * Scenario B: Chronic renal failure.

To get her mind off of all of this she draws‚ it helps get to her happy place in life so she doesn’t think about the worries in her life and going through dialysis.

In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around and bump into each other. Diffusion is one

Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes

HOW DOES DISEASE AFFECT THE LEVEL OF ORGANIZATION? * THE KIDNEY There are two kidneys‚ each about the size of a fist‚ located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus‚ it is filtered and the remaining fluid then passes along the tubule. In the tubule‚ chemicals and

PURIFICATION OF LACTATE DEHYDROGENASE FROM CHICKEN MUSCLE TISSUE Abstract The enzyme lactate dehydrogenase (LDH) catalyzes the last step of anaerobic glycolysis that is important for the normal function of the body. Purification of LDH is essential to understand its structure and function. The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of various. Analytical methods such as activity and protein assay were employed to determine
