Permeability NAME: LAB TIME/DATE: Simple Diffusion 1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? None of the solutes were able to pass through the 20 MWCO membrane. A possible reason to why none of the of these solutes were able to pass through was because the solutes could have been too big to be transported. According to your results‚ which solute had the highest molecular weight? The solute that

Diffusion through a Membrane Introduction Molecules are constantly moving. They move in straight lines unless they are deflected by other molecules or obstacles in their environment. Diffusion is the process by which the collisions between molecules cause them to continually spread apart from each other. Their movement can be described as movement from an area of greater concentration to an area of lower concentration. Diffusion continues until the molecules are equally distributed

The Lipid Barrier of the Cell Membrane‚ and Cell Membrane Transport Proteins The structure of the membrane covering the outside of every cell of the body is discussed in Chapter 2 and illustrated in Figures 2–3 and 4–2.This membrane consists almost entirely of a lipid bilayer‚ but it also contains large numbers of protein molecules in the lipid‚ many of which penetrate all the way through the membrane‚ as shown in Figure 4–2. The lipid bilayer is not miscible with either the extracellular

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

Andrea Koenigsknecht English Mr. Greenburg September 18‚ 2012 Following Through With Setting Goals I’ve learned valuable lessons in life about setting goals‚ taking the steps needed to reach my goals‚ and not giving up. There have been problems I have struggled with but I’ve learned to always be positive. Life throws many things at us but we need to adjust and continue on. I’ve learned things aren’t always easy‚ but with hard work‚ dedication‚ and focus I now realize I can reach any goal I

An application such as “PollEv” (http://www.polleverywhere.com/app) would be used for immediate feedback. It allows users to answer questions and vote throughout the session with immediate results sent to the presenter in an appropriate graph which can optionally be added directly into the slides to show the audience trends. Examples of questions are attached in appendix 2. The questions would be asked at the beginning of each new section in the presentation to gauge audience base understanding

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different
