Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

Kinetic Art Kinetic art: the art of motion. Kinetic art contains a/or several moving parts and depends on motion for its effect. The motion of the art work can be provided in virtually any way. It can be powered by natures elements; wind‚ wave power from water‚ or heat from a fire; It can also be powered mechanically through electricity‚ steam‚ clockwork using earths natural phenomena’s ‚ gravity‚ motors‚ or even through the observer such as cranking a handle‚ or giving a push.

Label five test tubes 1-5. Place 4 mL of 1 % starch in each of the first four test tubes. Place 4 mL of amylase solution in the fifth tube. Place all of the tubes in the 37°C water bath for 5 minutes. Obtain 5 clean droppers and label them 1-5. (To avoid contamination of these solutions

Introduction Reactions don’t always produce the same product‚ even if the reactants are kept constant. Some reactions have the capacity to produce two or more different products‚ depending on the reaction conditions and control such as thermodynamic and kinetic control. Thermodynamic control produces more stable products (University of Windsor‚ 2015). A kinetic control forms products at a faster rate faster rate because of its lower activation energy (UC Davis ChemWiki‚ 2015). By manipulating these

The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

Acetone is an extremely popular solvent that is used in rubber‚ resin‚ plastics‚ lacquers‚ varnishes‚ and rubber cements. It is also used in the creation of fats‚ oils‚ and waxes where is a primary component. Acetone has many uses in modern technology including those that relate to the medical field and various domestic uses. It is a very important organic compound found in everyday life‚ but it is also a toxin and can be an extremely dangerous environmental pollutant. Acetone has many valuable

Background of the Study Familiar household uses of acetone are as the active ingredient in nail polish removers and as paint thinner. Acetone can also be used for medical and cosmetic uses‚ such as applying acetone with alcohol for acne treatments to peel dry skin. It can also remove residues from glass and porcelain and it can also remove super glue from the skin. Perhaps‚ acetone is very useful in our everyday lives. Acetone is also known to remove ball pen marks on fabrics and clothings

But I think it happened because the blow dryer only focuses on one point so it doesn’t effect the other vanes. When I used the power of wind‚ I realized that the result was so much

solid surfaces in contact. Dry friction is also subdivided into static friction between non-moving surfaces‚ and kinetic friction (sometimes called sliding friction or dynamic friction) between moving surfaces. * Lubricated friction or fluid friction resists relative lateral motion of two solid surfaces separated by a layer of gas or liquid. * Fluid friction is also used to describe the friction between layers within a fluid that are moving relative to each other. * Skin friction
