Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase

Intro Hi my name is Marcus Harrison I’m here to compare and contrast the experiences of two story’s “A Walk to the Jetty” and “Kewaunee’s Ambition‚” And overall explain what it takes to be successful and the hardships that they went through to obtain their success. Body In the story Kewaunee’s Ambition there’s this girl named Kewaunee Lerma‚ she is a 17 year old student in a program called One Goal‚ which works with high schools in Chicago to help at-risk students by teaching them noncognitive

effect different temperatures have on the enzyme (Rennin‚ in milk) Introduction: Rennin is usually present in out stomach it helps us digest protein. Enzymes have optimum temperatures‚ since rennin is an enzyme from the human stomach its optimum temperature would be around 37-38 Celsius‚ optimum pH would be 1-3. If the temperature is too low the enzymes will move around slowly. A temperature that is too high or an incorrect pH would denature the enzyme. Materials: 25 rennin labels Beaker

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

Studying Literature in Grade 12 Graduating students in Ontario should only study Canadian literature in a Grade 12 English course. While good writers exist in all cultures‚ Ontario students should only study Canadian writers because we need to become more familiar with our literature. The reasons for this are the need to focus on our own Canadian culture despite being surrounded by other cultures‚ the need to promote and establish our own writers‚ and the need to encourage younger Canadian authors

Bio Lab Report Title: Gram-Negative and Gram-Positive contamination in yogurt. Introduction: There is bacteria that is beneficial and harmful in the human. Yogurt was choosed to be the best example that contains this bacteria. What happens to be the difference between these two types of bacteria‚ and how are they harmful? The bacteria is considered “Gram-Negative‚” and the substance is considered contaminated when there is more negative bacteria than positive bacteria. This will prove or disapprove

Bio 111-102 Homework #1‚ Lab 1 assignment My group examined the correlation between standing height and leg length in centimeters for ten of our classmates. Our supposition was that there would be a direct relationship and similarity between standing height in centimeters and leg length in centimeters. Therefore‚ our hypothesis was‚ if leg length increases‚ then standing height will also increase. 1) The steps for the scientific method are: • An observation is made • A question
