Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase (alpha-amylase)

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

Mechanical digestions starts from the intake of food into the mouth and when the food is chewed and while the food is broken down until it becomes small to be swallowed. Then the food goes down as a food bolus into the esophagus after the food is broken down. The food bolus passes through the alimentary canal through peristaltic movements. Peristaltic movements is a systematic series of muscle contractions and relaxation which involves the passage of food bolus through the esophagus‚ stomach‚ small

Department of agriculture- digestive system of a cow‚ koala and dingo Digestion comparison Koala The Koala is the only mammal‚ other than the Greater Glider and Ringtail Possum‚ which can survive on a diet of eucalyptus leaves. Gum leaves contain only about 50% water‚ very little nitrogen‚ large amounts of fibre and potentially toxic oils. Koalas are found to have molars premolars to physically break down the food. Plants contain cellulose‚ which can only be broken down to release cell contents

Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the
