The follow experiment was prepared, conducted and analysed in order to test at which pH level starch will be digested at fastest. The digestive system is a complex network of organs as well as other structures which all work together to supply the body with the necessary nutrients and energy required. If problem occurs along the digestive tract the consequences can be fatal. Therefore it is extremely important to understand your body’s requirements and the way in which it functions, especially when engaging in one of the most crucial and rewarding activities; eating!

    Unit 4 Assigment

    The first digestion process starts at the mouth in which cooked starch is reduced into simpler sugars by the action of ptyalin. Digestion of the remaining cooked starch is completed by amylase in the small intestine where duodenum and pancreas take part. Absorption of simpler sugars as the products of digested starch, take place in the small intestine as well. The digestion of proteins starts in the stomach in which protein molecules are reduced into amino acids by the action of hydrochloric acid and the protein digestive enzymes called proteases. Digestion of the remaining proteins is completed at the small intestines by the action of trypsin, and the amino acids are absorbed into the blood stream. Digestion of lipids starts at the small intestines in which fats and oils are emulsified and digested by the enzyme called lipase into fatty acids. Vitamins and minerals are generated and absorbed in the large intestines. The discussion will focus on the digestion of ingested…

    Unit 4 Report Distributing Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body. In Module 3 we followed the food through the digestive system and considered the process that takes place in the digestive system. The pizza that was eaten by Matt and Maria contained ingredients composed of fats, proteins, carbohydrates, and other components such as minerals, water and vitamins.…

    Human Digestion Summary Sci 241

    We all love to eat. I remember my parents used to tell me that in order for my food to digest properly, I would have to chew it one hundred times on both side to make it small as possible. They said that if the food was smaller it could digest quicker and easier. But most people do not know what happens to their food after they have chewed it up and swallowed it. Some may think that right after the food is swallowed, it goes straight to the stomach. The purpose of this essay is to discuss the path food follows as it goes through the digestive system.…

    amylase lab report

    The purpose of this lab experiment is to investigate factors that can affect the porcine pancreatic amylase enzyme activity in different environments such as the temperature, pH and also how being stored in extreme temperatures can affect the activity of the amylase. The activity of the amylase is going to be determined by the presence or absence of starch in the samples over time. There are some hypotheses on the Effects of temperature and pH; as I add the amylase to the starch in different temperatures the reaction’s rate increases in high temperatures; I belive that the amylase will work better. As the environment grows warmer, the amylase is going to become more energetic and more effective. Amylase is affected by environmental pH. I predict that the amylase activity will work best at a pH 7. As the pH changes from this point I predicted that the amylase activity is going to decrease and eventually stop. If I boiled and froze some amylase solution, and try to digest starch with at it at room temperature, I predict the previously-boiled and frozen amylase will not…

    bio short essay

    Once I have taken a bite out of my delicious favorite meal, the digestive system gets to work. It all begins in the mouth, chewing the food small enough to swallow. Salvia is squirted into the food to moisten and soften the food. Salvia contains enzymes, which break down the starches in food. Once the tongue forms the food into a ball to be swallowed, it is sent down the pharynx. The pharynx contains sphincters that help keep your food down once you swallow. Next, it makes its way to the esophagus, which is simply a transportation tube from the mouth to the stomach. It then reaches the stomach, which uses chemicals to make the food particles tinier. These chemicals are called gastric juices and include hydrochloric acid and enzymes. Once the stomach mixes with the chemicals, it is formed into a cream-like liquid called chyme. The gallbladder takes over from here hitting the food with more chemicals, one of them called bile. Bile is mixed with our food breaking down the fat into droplets, which will supply us with energy later on. From there, the pancreas uses digestive juice to break down…
