Human Digestion April 27th‚ 2014 SCI/241 Erica Leath The digestive system is a very interesting process that takes place after we have eaten a meal or a snack. The digestive system is responsible for breaking down the food that we have eaten and sending the nutrients to the different places in the body. The digestive is so amazing because it recognizes what your body needs and does not need and understands how to separate the two. Just like everything else in our body‚ the digestive
Free Digestion
Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also involves creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver

Purpose The purpose of the lab is to determine how different factors affect the digestion of starch. Starch is a type of complex carbohydrate with large polysaccharide molecules that are made up of hundreds of glucose subunits. The digestion of starch begins in the mouth with the enzyme amylase and continues in the small intestine. Maltose‚ a disaccharide‚ breaks down the large polysaccharide molecules. Maltase‚ also found in the small intestine‚ splits each maltose molecule

Identification of unknown a-Amylase through testing different temperatures and pH values to detect the absorbance of maltose. Introduction: Enzymes are biological catalysts‚ mainly proteins for this experiment‚ generated by an organism to speed up chemical reactions. They have active sites on which the substrate is attached‚ and then broken up or joined. For this experiment we are going to work with the enzyme a-amylase. Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human

help your body to digest food but do not have food pass through them. Accessory organs of the digestive system include the teeth‚ tongue‚ salivary glands‚ liver‚ gallbladder‚ and pancreas. To achieve the goal of providing energy and nutrients to the body‚ six major functions take place in the digestive system ingestion‚ Secretion‚ mixing and movement‚ digestion‚ absorption and excretion. There are two kinds of organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine

Abstract This lab was focused on determining the optimal temperature of the enzyme amylase responsible for catabolizing starch polymers and to see how different temperatures affected the rate as well as how effectively the enzyme worked. To proceed with the experiment the group set up four different test tubes for each‚ bacteria and fungal amylase‚ and labeled them accordingly with different temperatures as well as different solutions . Then the spot plates were placed on the time and temperature

Digestion define as a process where foods been breaking down by enzymatic action in the Gastrointestinal tract (GI tract) into nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

fragments. This step is made possible by the contraction of the muscle of the stomach‚ the muscularis. Composed of three layers of fibers arranged longitudinally‚ circular and oblique‚ it mixes and kneads the food. Then begins the chemical digestion. Only the digestion of proteins begins in the stomach. The mucosa contains glands that secrete gastric juices. Under normal conditions‚ the production of juices is 2 to 3 L per day. Hydrochloric acid and enzymes are also produced by cells of the stomach. All

Treating Starch How are starch and cellulose treated to allow them to be used in yeast? Starches: · All potable alcohol and most fermentation industrial alcohol is currently made principally from grains. · Fermentation of starch from grain is somewhat more complex than fermentation of sugars because starch must first be converted to sugar and then to ethanol. · Starch is converted enzymatically to glucose either by diastase presents in sprouting grain or by fungal amylase. · The resulting
