Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

is the movement of water across a membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells do not

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

THE EFFECT DIVORCE HAS ON CHILDREN In today’s culture‚ divorces have come to be a mean in our lives. Married people these days are getting separated due to various problems‚ moreover because of struggles in the marriages‚ lack of passionate feelings‚ marriage couple cheating on their spouse‚ and other kind of marriage difficulties. Furthermore these divorced couples have kids that are young‚ who have no idea on how to deal with an event like a divorce. The effect touches all growing stages of children

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1]. Aerobically‚ sugars such as glucose are transformed into pyruvate [2] and then into Acetyl CoA. This is then put through the citric acid cycle which is a series of reactions that oxidize acetyl units into carbon dioxide [2]. Following
