turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable to starch. 4B- The hypothesis was supported because the diffusion rate was faster shown from the agar blocks. The materials passed through the membrane easily and quickly in the small cells than the large‚ making them more efficient. The smaller the cell is‚ the faster it can transport signals. The bigger cell

influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent was to measure
Premium Osmosis Diffusion Chemistry
Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

Lab Report #1 Facilitated diffusion By: Kelsey Clark Biology 2401 C1L Dr. Fanini October 2‚ 2017 Facilitated Diffusion Facilitated Diffusion is a type of passive transport that allows for lipid insoluble molecules or molecules that are too large to pass through a membrane. The molecules are able to pass through by binding with protein carrier molecules and moving down the concentration gradient. The rate of diffusion will continue to increase until the carrier proteins are saturated

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids. Materials and methods: * 20 mwco dialysis membrane * 50 mwco dialysis membrane * 100 mwco dialysis membrane * 200 mwco

Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through
