Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The

Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

In the movie Apollo 13 three astronauts go up to space in the space craft odyssey and encounter many problems. The astronauts‚ Jim Lovell‚ Jack Swigert and Fred Haise were on a rushed mission to go to the moon when Jack went to go stir the oxygen tanks and one of them exploded. The explosion led to a whole host of problems. The astronauts had to abort the mission and focus on a safe return home. A monomyth plotline is when a person leaves a place‚ encounters obstacles and comes back a different

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

Other people feel that it is important to rest the mind during leisure time. • You should write at least 250 words. • You should spend about 40 minutes on this task. In generally‚ people agree that leisure time is important for everyone. We feel tried ourselves after the work‚ the study‚ than we want to spend little time for doing what we want. However‚ everyone like to do another types of activity. Some people

If we do‚ we will face consequences. Leviticus 19:13 "Don’t exploit your friend or rob him. Don’t hold back the wages of a hired hand overnight.” This one is similar to the passage spoken in Leviticus 19:11 but I think it relates more directly to the fact that as part of business ethics we should not

Trisomy 13 Trisomy 13‚ also known as Patau Syndrome‚ is a chromosomal abnormality where an individual has an extra chromosome 13. Trisomy 13 was first recognized by Patau and his colleagues in 1960 (Matthews‚ 1999). It affects approximately 1 in 12‚000 births and is the least common of the trisomy syndromes‚ after trisomy 18 and trisomy 21 (Down syndrome). An abnormality of the chromosome occurs when mitosis or meiosis does not happen correctly. During mitosis‚ when the cells are dividing

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and
