    Simple Diffusion Activity 1: Simulating Simple diffusion 1. What is the molecular weight of Na+? 22.99 or 23 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through?50‚100‚ 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin was too large to diffuse into the right beaker. Activity 2: Simulating Dialysis 6. What happens to the urea concentration

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

    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

    Where as the active transport requires energy from the molecule to be moved. 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

    Answers to Questions Activity 1: Simulating Dialysis (Simple Diffusion) (pp. 2–4) 9. All solutes except albumin are able to diffuse into the right beaker. Using distilled water in the right beaker and either the 100 MWCO or 200 MWCO membrane will remove urea from the left beaker and leave albumin If the left beaker contains NaCl‚ urea‚ and albumin‚ you can selectively remove urea by dispensing a concentration of NaCl into the right beaker equivalent to that in the left beaker and by using

    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

    this occur? It happened because the more concentrated it became it causes the molecules to move down. Facilitated Diffusion Activity 3: Facilitated Diffusion 1. At a given glucose concentration‚ how does the amount of time it takes to reach equilibrium change with the number of carriers used to “build” the membranes? The time is faster to rach the equilibriums. 2. Does the diffusion rate of Na+/Cl- change with the number of receptors? YES 3. What is the mechanism of the Na+/Cl- transport

    of the cell. An important part of regulating this is passive transport. Passive transport is the movement of materials through membranes without any input of energy. One type of passive transport is diffusion. Passive transport is the diffusion of substances across a membrane. In diffusion‚ molecules will usually move from where the substance is more concentrated to where it is less concentrated. The molecules also tend to spread out in the space they enter just like food coloring in water

    Diffusion is the process by which a particular phenomenon --- such as a contagious disease‚ a technological innovation or even an idea --- is spread from person to person over a period of space and time. One method of diffusion is known as expansion diffusion‚ which is broken down into three distinct types. Expansion Diffusion * Strictly defined‚ expansion diffusion is the process of spreading something from one place to another in an ever-expanding "snowballing" process. Expansion diffusion
