Sterling Hayden AP Biology Mrs. Proehl 24 November 2014 I. Title Effect of Differing pH‚ Temperature‚ and Enzyme Concentration on Catalase Reaction Rate II. Introduction Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

The Physiological and Anatomical Similarities of the Human and Fetal Pig Body Abstract Through the dissection of the fetal pig‚ we were able to compare and contrast the structure and functions of the organs to those of a human. We dissected the pig and observed all the exterior and interior structures. We found that because both are mammals‚ the fetal pig’s structure was almost identical to the human body. Intro Since humans and pigs are both mammals‚ it can be very useful to study the

was to observe the effect of temperature and pH on the reaction of barley alpha-amylase enzyme with starch substrate and establish the optimum temperature and pH for this reaction. The optimum temperature and pH for the reaction of alpha-amylase and starch was predicted to be a temperature of 50°C and a pH of 5. The optimum temperature and pH for the reaction was determined by monitoring the reaction rate of alpha-amylase at different temperatures and pH’s by means of using a spectrophotometer to measure

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye
