Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Cell Transport And Homeostasis The roles of different types of cell-membrane proteins in the preservation of body organs donated for transplant is very vast. Certain cell-membrane proteins carry several different types of nutrients that are beneficial and are sometimes very important to keep organs that are to be transplanted healthy and fresh. Organic nutrients are some very good preservers. One of the most transplanted organs is the kidney. It is important that this organ has nutrients

The Effect of Temperature on Beet Cell Membranes and Concentration of Betacyanin Released Introduction Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell et al.‚ 2008). Each membrane layer is composed of a phospholipid layer‚ which is semi-permeable and possesses the ability to control the movement of diffusion. Within the centre of a cell‚ the vacuole that is responsible for storage and

TITLE AND AUTHOR Lab 7 Analysis of purified Concanavalin A via:Hemagglutination INTRODUCTION The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions
