this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic 20 at a wavelength of 540 nm

Due to reaction time when using a timer the exact rate of reaction of the catalase activity cannot be determined. The time the liver reacts with the solution varied with the sample of 3 for each temperature. Because the reaction initiates as soon as the reactants make contact catalase activity would be higher than the true value in the results. Another possible error is that the

If the liver shuts down‚ the body can only live a couple of days. The liver is a storage place for iron‚ vitamins‚ and sugar that the body needs for energy. The liver also helps cleanse the body of waste products‚ poisons‚ and drugs that could potentially harm the body. When Hepatitis attacks the liver it affects the liver’s abilities to store iron
