Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

MARK333 Case Study – Cadbury Digestives Amanda Kelln 4969546 1. The ‘Thank You’ campaign worked so well because Cadbury did plenty of research on their target audience and then implemented an advert to deliver a particular message to this specific target audience. To be more specific‚ Cadbury determined from their research that their target audience was primarily women chocoholics who were looking to experience chocolate guilt free. Once the company determined this‚ they then implemented an advert

Not only is it the location of the “Restricted Ward” where a disaster resulted in the disappearance of thousands of people‚ but it is also a city rife with murders. Dragging down the health and safety rating of the city even further are the “Unions” who are people with inhuman abilities and a penchant for havoc. In the middle of all of this is Touya Kagari‚ an ordinary high school student who lost his mother to the disaster in the Restricted Ward. Touya was adopted by the sister of one of his classmates

The digestive system is a group of organs that perform the process by which food‚ containing nutrients‚ is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands

chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break down of macro food molecules to smaller ones. The digestive process also involves creating waste to be eliminated. The digestive track (gut) is a long twisting tube that starts in the mouth and ends at anus. It’s made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones‚ to aid in

LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because
