Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

Powder Story Analysis Powder is a straightforward story about an adolescent boy and his father on a ski trip. It is a first person story; written from the boy’s point of view who is also a central character in this story. The parents are separated or divorced; the father has promised to have the boy back to his mother in time for Christmas Eve dinner. But the father tarries‚ deciding to get in a few more runs‚ and by the time they set off‚ the mountain road they must take is closed and guarded

Banana and Papaya Fruit Peelings Extract as an Alternative Culture Medium for Fungi Submitted by: Maricel P. Clores Catherine A. Bernardo Rodora Lafiguera Julius Jorge Suarez Scope and Delimitation This study is focused on how to produce ointment out of banana and papaya fruit peelings extract to help avoiding fungal infections. It must be done within a laboratory. The place must be conducive for only a matter of years. This study builds upon on how to lessen fungal

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

Carbohydrate Powders: During an intense weight training workout‚ the glycogen stored in the muscles and liver is the main energy source. Optimal strength and endurance during your workouts it is very important that these glycogen supplies are completely restored before starting a new workout. The best moment to replenish exhausted glycogen supplies is during the first 2 hours after the workout. Easily digestible food products containing lots of fast absorbing carbohydrates high glycemic index are

Two such short stories are “Reunion” and “Powder”‚ these stories are about the father-son relationship in a broken family. The “Reunion” by John Cheever ends in a way with the son’s disappointment

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity

two Title: Enzyme Function Purpose: To observe the role of enzymes in chemical reactions and to determine the kinds of cells that contain more of the enzyme catalase. Prior Knowledge: Enzymes are proteins that assist the chemical reactions of a cell by lowering the amount of activation energy needed to start the reactions‚ thereby enabling the cell to carry out the reactions at a faster rate; enzymes that lower the activation energy are therefore called catalysts. Moreover‚ the enzyme itself is

Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the
