Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

catalyst is called biological catalyst‚ and enzyme is an example of biological catalyst. Enzyme is very important for biochemical reactions‚ as it helps the reaction to become faster than usual. The reactions with enzymes will react 10 billion times faster than those solutions without enzymes. (clitoncc)The enzymes can only react with one particular reaction‚ in order for the reaction to react it needed to find the correct enzyme. (uab) Rennin is an enzyme produced in the inner lining of the abomasum

experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius.

Poultry or beef? Which meat is healthier for us to eat? Due to the importance that society today has put on our health due to health consequences and prices differences I am choosing to compare and contrast poultry and beef. Although many of us may think that chicken is so much healthier then beef‚ I will show to you that each of the meats have their own good and bad purposes in or healthy lifestyle habits. For me it all started about two years ago when my best friend was in the emergency room

have a cancer that has already spread to the liver or they will come back in future years with metastatic cancer to the liver.” Liver cancer‚ or other known as Hepatocellular Carcinoma‚ is a cancer residing in the liver. There are other cancers like metastatic cancer that starts at other organs then spreads to the liver. Being the third most common cancer in the world‚ it is also one of the deadliest. Twenty percent of the patients that are affected by liver cancer survive for a year after diagnosis

chronic liver disease. Liver disease is any condition that causes liver inflammation or tissue damage and affects liver function. Some important function of liver are to convert the food we eat into stored energy and chemicals necessary for life and growth‚ to act as a filter to remove alcohol and toxic substances from the blood‚ and to manufacture and export important body chemicals used by the body. Liver disease is dangerous and it can effect the body. The liver has many functions‚ so liver disease

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase.

Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase

Introduction To determine the effects of stressful experimental treatments on living membranes we are going to examine how fresh beets roots react when they are exposed to different temperatures. Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell 133). They organize specific chemicals and reactions into specific compartments within the cell. Generally‚ cell membranes consist of phospholipids
