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...

Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

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...

Amount Of Light Fiber Optics
1,073 wordsEverything You Ever Wanted to Know About dB But Were Afraid to Ask Telecommunications systems used electrical signals and copper wire to transmit voice messages long before lasers, lightwave's and fiber optic cable. To describe and measure power levels in electrical systems, telecommunication engineers used the standard unit of decibels to express gain or loss and relative power levels. Meanwhile, scientists working with fiber optic signals were using units of milli watts (mW) to determine the a...

Amino Acids Living Organisms
979 wordsProteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word proteins or primary. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions are the m...

Carbon Dioxide Surface Area
3,396 wordsOne of the most little known species of ants in North America is the leaf-cutter ant. This is mainly because it lives in tropical environments and it is not aggressive to animals or humans if not disturbed. The leaf cutting ant is a social insect. Alone the ant is virtually helpless but with the colony it can be a thing feared by animal and human alike. The leaf-cutting ants have a very important role in the tropical forest. They create and manipulate the environment around them. They also can d...

Internal And External Point Of View
1,124 wordster>Sam Vaknin's Psychology, Philosophy, Economics and Foreign Affairs Web Sites Knives and forks are objects external to us. They have an objective - or at least an intersubjective - existence. Presumably, they will be there even if no one watches or uses them ever again. We can safely call them "Objective Entities." Our emotions and thoughts can be communicated - but they are NOT the communication itself or its contents. They are "Subjective Entities", internal, ...

Plan for pH I am going to use the three categories of acid, neutral and alkaline to test how pH affects the rate of the enzyme rennin. Whilst studying the affects of varying the pH, I am going to ensure that all other variables are constant. Therefore, I will continue to use 2 ml of milk and 4 drops of rennin.

Thinner Ink Films Thicker Ink Film Printing
402 wordsTo ensure proper trap the ink tack units vary by one or two units from printing unit to printing unit. The highest amount of tack should be on the first unit proceeding to lesser tack values as the paper travels to the further printing units. On the other hand as you progress printing units the ink film thickness should increase. The reason for this is because thinner ink films will not trap properly on thinner ink films. Optical density is used as a checkpoint, therefore color strength of the i...

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...

Investigation On The Enzyme Trypsin
2,197 wordsAn Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify when the gelatine is digested, when the photog...

Amino Acids Peptide Bonds
367 wordsA gastric gland is a tubular structure in the vertebrate stomach that secretes gastric juices. The gastric glands have three types of cells that secrete different components of the gastric juice. One of them is being a chief cell, which is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin begins the digestion of proteins in food. Pepsin is a Peptidases, which is an enzyme that breaks peptide bonds of proteins. Pepsin is found in the mucosal lining of the stomach that br...

Hydrogen Peroxide Degrees Celsius
539 wordsCatalase Which Is Found In The Liver' Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction then takes place and the molecules of product leave the acti...

Organic Molecules Life Span
525 wordsThe expression of genes is very complicated and is regulated by a number of things. Something that has a major effect on enzyme regulation and stability is temperature. Since enzymes are biochemical catalysts, made up at least partially of protein, they are sensitive in varying degrees to heat. Raising temperatures of the environment generally multiplies the degree of activity by the enzyme. Once an optimum temperature has been reached, however, temperatures that are too high will denature the e...

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

Printing Process Requires Printing Process May Begin Screen
437 wordsThe Hybrid Printing Process INTRODUCTION The printing for hybrid circuits is a fundamental process in which the conductors, resistors and overglaze are put onto a ceramic tile called a substrate. While conductors, resistors and overglaze are not printed at the same time, the process is the same. Thus it is very important that anyone who is in the microelectronics field should know the basic process. While the process may change, depending on technology used, the same basic principles will remain...
