Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and

llo 13 [pic] Apollo 13 Problem Solving Using SPICES 1. What situation is the movie Apollo 13 about? They want to go to the moon and land on it. 2. What was the big problem that happened during the movie? There isn’t enough power to come back to Earth. This is the big problem because all the other problems branch of from this issue. 3. List three smaller problems that also came up in the process of trying to fix the big problem. They can’t land on the moon‚ because they were

Enzymes are biological catalysts that operate at the temperatures‚ pressures‚ and moderate pH values found in living organisms. They help in a faster chemical reaction in our human body. Besides this‚ enzymes also play a huge role in various industries. The following paragraphs will talk about how various enzymes are used in various industries : The Dairy Industry and Medical Industry. In the dairy industry‚ the enzyme Protease is used widely. While making cheese‚ protease helps coagulate milk

Apollo 13 The Apollo 13 mission was a significant historical event‚ because of the dangerous repercussions that followed the explosion of the oxygen tank on Apollo 13. The story in which the astronauts Lovell‚ Swigert‚ and Haise surviving these errors during the flight is truly incredible. In the movie Apollo 13‚ the creators depicted most of the events involving the crew’s adventure to and from space quite accurately. Although creating most events successfully the creators of Apollo 13 failed

Connecticut‚ Delaware‚ Georgia‚ Maryland‚ Massachusetts Bay Colony‚ New Hampshire‚ New Jersey‚ New York‚ North Carolina‚ Pennsylvania‚ Rhode Island‚ South Carolina‚ and Virginia. Out of these 13‚ Virginia‚ Rhode Island‚ and Pennsylvania stood out to me the most. Even though these three colonies have differences based on how they started‚ who governed them‚ and how they were governed‚ they still have many similarities. 1607. Jamestown‚ Virginia.

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
