Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

Petri Dishes Test Tubes
899 wordsControlled Comparison: During class, our instructor set up the same lab that we were doing with 2 solutions, both of which were known acidic or basic. He placed 2 ml of the known acid into 2 different test tubes, and 2 ml of the known acid into 2 different petri dishes. Then using forceps, he tested blue litmus paper in one petri dish, and red litmus paper in another. The blue litmus paper, after being dipped into the solution, turned red in reaction to the acidic solution. While the red litmus ...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Three And Four Reaction Rate
859 wordsTitle: Examining Some Properties of the Enzyme -amylase In this experiment a deeper meaning in the catalysts of reactions is studied. Catalysts accelerate chemical reactions without permanently changing the reaction. Enzymes, catalysts in biochemical reactions, are globular proteins which lower the activation energy needed to begin a reaction and therefore increase the rate at which efficient reactions can occur. Proteins (henceforth enzymes) are complex molecules made of amino acids in polypept...

Family And Friends Interracial Dating
631 wordsMany interracial couples are faced with negative reactions from society, making it hard for them to have a regular relationship. They have to deal with disapproval from their own race, pessimistic reactions from family and friends, and not to mention the ignorance of society as a whole. Why is interracial dating so controversial? Is not racism a thing of the past, or is that what we would like to believe? People who date and socialize with people of different racial groups frequently experience ...

1,714 wordsWith the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e. g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate S...

Adverse Reactions Chicken Pox
1,032 wordsIn 1996 a mother took her six-month-old son, Jonah, to the doctor to get his DPT vaccination. Two days later, Jonah came down with an ear infection. Bobbie took him into the doctor and the child was given a prescription of amoxicillin. The ear infection soon healed and all went well for about two months when the infection returned. Bobbie again took Jonah to the physician where he, this time, gave the boy a stronger form of amoxicillin. Again the infection soon diminished. About four months late...

H 2 O 2 O 2
828 wordsPurpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...

Sympathetic Nervous System Fight Or Flight Response
1,673 wordsby Ingrid M. Cordon (spring 1997) At one time or another, most people experience stress. The term stress has been used to describe a variety of negative feelings and reactions that accompany threatening or challenging situations. However, not all stress reactions are negative. A certain amount of stress is actually necessary for survival. For example, birth is one of the most stressful experiences of life. The high level of hormones released during birth, which are also involved in the stress re...

Lazarus argues that we cannot assess the origins of stress by looking soley at the nature of the environmental event, rather stress is a process that involves the interaction of the individual with the environment. These categories are based mostly on one's own prior experiences and learning. Also, each of these categories generates different emotional responses. Harm / loss stressors...

Negatively Charged Positively Charged
571 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...
