EnzymeMay 19, 2012
Enzymes enable molecules called substrates to undergo a chemical change to create new molecules called products. Each substrate fits in a specific area of the enzyme called the active site similar to lock and key mechanism.
Enzyme AnimationMay 22, 2012
A rundown of enzyme functions, how it works and what it does. Made for a biology project.

048 - Enzymes Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The importance of cofactors and coenzymes is emphasized. Competitive and allosteric inhibition is also included.
Enzyme function and inhibition (with audio narration)May 22, 2012
This was created over a couple of days to demonstrate how a simple animation can be used as a learning aid for scientific concepts that may be difficult for a student to grasp. The audio came out quieter than expected, so you may have to turn up your speakers slightly. In the above animation, the normal enzyme catalytic cycle is shown and is followed by two types of inhibition by competitive and non-competitive blockers. Feel free to contact me if you have any questions or comments.

Digestive Enzymes, Nutrition and Your HealthMay 25, 2012
Nutrition by Natalie Information about Digestive Enzymes Digestive Enzymes are enzymes that specifically work in the digestive system to facilitate the digestion, absorption, and transportation of nutrients. They also work to promote timely elimination of digestive waste products that are not of use to the body. Without enzymes, our cells would not get adequate nutrition and we would not survive. Enzymes function as catalysts to enhance and dramatically speed up biochemical reactions that occur in every one of our cells. They are only activated in water, so staying hydrated is very important for enzymes to work effectively. Enzymes must be present to ensure proper digestion of nutrients, energy production, metabolism, transportation of fluid to cells, and elimination of toxins among many other functions. Enzymes exist in foods to help our body's breakdown what we eat. Raw, uncooked foods are the only foods that contain enzymes. Since the majority of our diets are cooked foods, we significantly limit the enzymes available in our food for digestion, thus putting more stress on our digestive systems. Some supplemental enzymes should be taken with food to enhance digestion and absorption of nutrients, whereas other supplemental enzymes should be taken on an empty stomach to support circulation, decrease inflammation, support our immune systems and combat stress. Imbalances in these factors have been scientifically proven to be associated with or the cause of numerous diseases ...
Learn Biology: Cells—EnzymesMay 24, 2012
SALE TODAY: Learn Piano on iOS bit.ly Mahalo biology expert Mary Poffenroth explains what enzymes are and how they work in our bodies. Enzymes --------------------------------------------------------------------- Enzymes are large molecules made of protein that catalyze, or increase the speed, of chemical reactions in organisms. Without enzymes it would be impossible for these chemical reactions to occur at the speed of life. Enzymes lower the activation energy, or the minimum amount of energy needed to start a chemical reaction. They are very selective and are never used up; enzymes can be used over and over again. In animals and humans, enzymes are essential for breaking down our food - proteins, fats and carbohydrates are broken down so they can be absorbed through our intestinal walls.www.youtube.com Type and Use --------------------------------------------------------------------- Each type of enzyme is specialized for a specific reaction and has a unique 3-dimensional structure which allows it to fit with the substrate, at its active site, to facilitate a reaction. Enzymes are needed for all of the biochemical reactions that occur in organisms, including those related to digestion and functioning of the circulatory, immunological, nervous and muscular systems in vertebrates. There are various inherited disorders in humans that result in enzyme deficiencies, such as mucopolysaccharidosis and Nieman-Pick disease. Enzymes are also necessary in food microbiology for the ...
