The purpose of this lab was to hypothesize about membrane traffic in lab‚ explain the differences between the solutions hypertonic‚ hypotonic‚ and isotonic and how they respond using the understanding of the cell membrane structure‚ types of transport mechanisms such as active‚ passive‚ diffusion‚ osmosis‚ and explain the movement of particles moving across the cell membrane. In this lab was divided into two parts. The first part was varying the concentration and the second part was varying the temperature

Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

affect the beetroot cell membrane‚ I will keep the temperature constant throughout the experiment by using a water bath and measuring the desired temperature using a thermometer. PH: I will make sure that the pH is stable (constant) and only the temperature varies this is to be done by using buffer in every test tube so as to maintain pH balance for each beetroot sample and insure that pH does not become a variable. PH is important for maintaining the integrity of the cell membrane as integral proteins

Implementation My aim for this experiment was to find the effect of temperature on the membrane permeability of beetroot. Since I was unfamiliar with this experiment‚ I first conducted a preliminary test. I considered my preliminary test as my trial for this experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying temperatures. Betalain pigment found in beetroot My method for this experiment is:- * Use a cork borer to cut about

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
