The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

U.S. Corporate Taxes and Reform The current U.S. corporate income tax system has many flaws and with the correct changes the United States budget deficit could transform into a surplus. There are two clear flaws in the current corporate income tax policy. The first is the high tax rate corporations pay in the U.S.; taxes on corporate income are currently at 35%. This burden causes businesses to avoid operating here and the cost is thousands of domestic employment opportunities. The next

of the experiment investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower the temperature

1.0 Introduction This assignment is based on a study of alcohol metabolism and its impacts to human health. The assignment explains that how the body can dispose of alcohol and discern some of the factors that influence this process and influences of the process to the metabolism of food‚ hormones‚ and medications. 1.1 History of alcohol The word “alcohol” appears in English as a term for a very fine powder in the 16th century. It was borrowed from French‚ which took it from medical Latin.

focused on determining the stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were determined in order to conclude which alcohol and concentration of alcohol had the greatest effect on biological membranes. The results showed

Depending on what stressors there are the cellular membrane can become damaged. The objective of this experiment was to examine the structure of the cell membrane using the beet root model system by observing the effects of solvents on the beet root

The Effects of Drinking Alcohol Alcohol also known as ethanol contains high amounts of intoxicating supplements that are very dangerous to the body. If consumed in high amounts or at a young age‚ it can severely damage parts of the body such as the liver‚ brain‚ and it can eventually lead to death. If people are not careful they can become addicted to alcohol‚ due to it being classified as a drug. Most young adults‚ aging from fifteen to twenty‚ do not take their first drink out of their own

postsynaptic ending that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors. The receptors that alcohol binds to are the ones for acetylcholine‚ serotonin‚ gamma aminobutyric acid‚ and glutamate. The two neurotransmitters that distress the behavior effects from alcohol are the gamma aminobutyric acid and glutamate.

To find 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
