oFacilitated diffusion can only move in one direction from high concentration to low concentration‚ which is with the gradient. Where the active transport can move from both low concentrations to high concentrations‚ therefore it can move against the gradient where as the facilitated diffusion can not. The process of active transportation is when a molecule work together with the active side of a protein section‚ which this triggers an energy enzyme reaction that produces a shift in the section

You may be wondering what diffusion‚ tonicity‚ osmosis and semipermeable membrane is. I’ll start off by explaining semipermeable membrane. A semipermeable membrane relates to the dialysis lab #1 because in dialysis tubing is considered semipermeable barriers. Semipermeable membrane is a membrane that allows passage of some particles but not others. (Lab manual) Diffusion on the other hand‚ is a form of passive transport where particles move down their concentration gradient from a region of high

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

Nikhil Gopalam October Mailbox #55 Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute

simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse faster because it is more concentrated. We graphed the diffusion of chloride

How does diffusion affect the rate of growth? If I placed a gummy bear in various solutions‚ then the gummy bear would change in size‚ because diffusion and osmosis cause the gummy bear to react to the solution’s molecules‚ and further affects the gummy bear’s mass. An experimental lab conducted in class was tested‚ essentially to observe the effects of diffusion/osmosis. More specifically‚ according to‚ “merriam-webster.com/dictionary/diffusion‚” the process of diffusion causes particles to spread

One purpose of the experiment was to gain an understanding of diffusion and osmosis‚ specifically in context of a plant or animal 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

spread faster‚ because the particle in the hot water have more kinetic energy than the cold water‚ so it will spread faster. Particles at a higher temperature are moving faster than particles at a lower temperature‚ that is one of the law in particle theory. It spread slower in cold water‚ because the particles is moving slower than the hot water‚ when the water cool down the particles start to lost kinetic energy and they slowly clump together and vibrate. Procedure: First gather all the materials we
