There are many kind of cell membrane disease‚ There are : Cystic Fibrosis Cystic Fibrosis is a disease that cause by gene mutation of CFTR Protein. CFTR it’s stand for Cystic fibrosis transmembrane conductance regulator. This disease causes too much production of thick mucus‚ then the mucus will blocked the ion transport in epithelial cells that line the passageways of the lungs‚ pancreas‚ and other organs. If the passageways of the lungs is blocked by the thick mucus‚ it will make the sufferer

out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane. So at 10%

efficient. This is when ethanol made its debut into the fuel industry‚ as an additive to gasoline. Ethanol is put into gas as a combatant against water‚ which can find its way into fuel tanks of vehicles. It reduces the effect that this water has on the health of the vehicle‚ and as a result increases gas mileage‚ and also increases the amount of complete combustion. Ethanol consumption has severe drawbacks pertaining to its effect on the environment. Production of ethanol increases the formation

Effects of Sucrose Concentration On Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy

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

Title: Ms. K Cell Membrane and Homeostasis Experiment Objective(s): The reason for this experiment is to see how starch and iodine affect each other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and

Materials & Methods Brook trout blood was used throughout our experiment as our erythrocyte suspension‚ which consisted of ten drops of fish blood in a test tube containing 10mL of 0.7% NaCl. Eleven other solutions‚ (erythritol‚ xylose‚ monacetin‚ diacetin‚ triacetin‚ urea‚ thiourea‚ glycerol‚ ethylene glycol‚ glucose and fructose) all isosmotic but not necessarily isotonic with the cytoplasm of the erythrocyte‚ were combined with a 0.2mL of well-mixed stock suspension were added to 0.27M of each
