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

Some say that the idea of love in modern terms differs conceptually from that of earlier periods. That argument is demonstrably false. Although love has been characterized in many different ways throughout the ages‚ the fundamental idea remains constant. No matter the eccentric personalities love is entitled to‚ love is what it is. From a literary point of view‚ whether one reads the tender longing of Sappho‚ the unattainable desire of Petrarch‚ or the whimsical prose of Dickenson‚ the message

LAB REPORT 4 DETERMINING AN EQUILIBRIUM CONSTANT CAUSION 1. Potassium thiocyanate (KSCN) is hazardous 2. Wear protective material before performing the experiment. INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance

Understanding ion permeability is vital to knowing how it establishes a membrane potential‚ and how it eventually leads to the contraction of muscle cells. This was done using crayfish tail muscles. Lateral and medial tail muscles from the tail of a crayfish were excised. These muscles were then placed into solutions with different types of ion concentrations. Usage of different ion concentrations was necessary in practicing how to measure resting membrane potentials accurately. Measurements with

The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane

When estimating the effect of changes in the money supply to changes in nominal GDP‚ it is common to assume that the velocity of money is constant. The velocity of money is a measure of average number of times per year that a dollar is exchanged. The quantity theory of money states that the money supply multiplied by the velocity of money is equal to the price level multiplied by output. ( ) Price level multiplied by output is the nominal output. Therefore‚ a percent change in the money

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial
