For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

Aim To investigate the effect of different temperatures on the activity of rennin in milk Introduction Enzymes are globular protein‚ responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon‚ hydrogen‚ oxygen and nitrogen (Gunsch‚ 2012). The role of enzyme is to act as catalysts‚ substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

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

Enzymes are a major role in the process of accelerating chemical reactions. Environmental factors affect the enzymes‚ These environmental factors include ph levels and body temperature. While both of these environmental factors affect the enzyme‚ body temperature affects the enzymes the most and can result in death. Enzymes are affected by high body temperature. Enzymes are highly specific and they work at certain temperature levels depending if it’s hot or cold. However‚ when the

Effect of Temperature on Solubility Lab Purpose: What is the solubility of minerals in water? What is the relationship between temperature and solubility? Hypothesis: If salt and sugar are each tested in water of varying temperatures‚ then salt and sugar’s solubility will increase as the temperature also increases. Materials: Two 250 mL beakers Tap water 100 mL graduated cylinder Hot plate Two petri dishes Glass stirring rod Salt Sugar Thermometer

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which
