1. Liver disease can occur due to diabetes & so can diabetes occur due to liver disease. The liver disease occurring due to diabetes‚ primarily type 2 diabetes is called Non-Alcoholic Fatty Liver Disease (NAFLD). Type 2 diabetes is metabolic condition causing elevated blood glucose levels due to either the lack of production of insulin or the body’s inability to utilize insulin efficiently (PubMed‚ n.d). NAFLD or commonly called fatty liver‚ occurs due to impairment of the liver cells to effectively

catalase‚ located in the liver‚ is being used to break down the substrate. Problem The purpose of this lab is to see if the enzyme‚ catalase‚ can be manipulated. We are testing the effects of pH‚ temperature and enzyme concentration. Hypothesis Controlled When we add peroxide to the liver it will bubble a lot and break down faster. When we add peroxide to the liver it will not bubble a lot and it will not break down faster. pH When acid is added to the liver‚ it will increase the reaction

temperature on enzyme In a liver sample were observed under iced‚ boiling‚ 37 degrees‚ and room temperature Conditions. The enzymes became completely denatured under boiling conditions because they couldn’t take the intense heat. Enzymes performed in optimal conditions of 37 degrees. But When the enzyme were iced the enzymes reacted slowly. They stop because of the iced Conditions stopped them from moving freely‚

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

result of respiration. Urea is produced in the liver from excess amino acids. Where are the substances excreted? Carbon dioxide is passed from the cells of respiring tissues into the blood stream. It is transported in the blood (mostly in the form of hydrogen carbonate ions) to the lung. In the lungs the carbon dioxide diffuses into the alveoli to be excreted as we breathe out. Urea is produced by breaking down excess amino acids in the liver. This process is known as deamination. The urea
