CELL TRANSPORT MECHANISMS AND PERMEABILITY Zack Johnson Human Anatomy & Physiology Lab 2101 Instructor: Alan Byboth‚ M.S. 10/4/12 Abstract- The cell is invaluable building block of all biological life on this planet‚ and one of its most important and unique characteristics is its ability to be selectively permeable with its plasma membrane. This outer membrane’s sophisticated mechanisms of transport through its bilayer are vital in maintaining homeostasis in the cell and the entire

Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. It will also help to define diffusion and describe the process that occurs when certain solutes come in contact and are either stopped or move through the plasma membrane. Hypothesis I believe the plasma membrane is selective about what is able to and not able to pass

1a. Two reasons that the mass of the bag levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the

Computer Simulation of Cell Transport Mechanisms and Permeability: Passive Processes and Active Processes Introduction In this lab we will establish a difference between the two types of cell transport mechanisms and their permeability. The first type of cell transport is passive processes which are driven by concentration or pressure differences in the interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two main
