Digestion Essay Examples

Digestion of proteins begins in the stomach where an enzyme known as pepsin is responsible their breakdown. The enzyme breaks the peptide bond that holds the protein molecule into polypeptides. These polypeptides then move to the ileum where they are broken down by the pancreatic enzyme into smaller units known as peptides (Sherwood, 2015). The enzymes continue breaking down the peptides into amino acids, which are absorbed into the bloodstream. Plant protein sources are different from those of animals and hence there are some differences in their absorption. This is because animal proteins are the same as proteins that are found in the body and therefore they are absorbed more easily as compared to...

digestion and avoid overworking the body organs to break down the food. The author says that one should eat until he staggers because of the full stomach. This is unhealthy. The body exercise is very important for the proper working of the muscles. The healthy man used to wake up early in the morning and do some exercises before beginning the daily chores. The author argues that one should wake up when going to the work (“If your work begins at seven in the morning, get up at ten minutes to, but don't be liar enough to say that you like it”).Obviously, one cannot wake up five minutes to work’s time. The author also points out the cold bath is not beneficial to the health (Staines, 91). He...

digestion process. In a nutshell, philosophical science points out various demarcations of non-science from science. Science is open to abandonment, constant corrections, or revisions of theories and hypothesis. Therefore, science has a significant impact on the human life. References Cziko, G.

digestion and absorption of lactose within the small intestine. Since it has been properly documented that most of the individuals suffer from primary hypolactasia below the age of 20, this research introspect was conducted to convey evidence that hypolactasia could also be found in individuals above the age of 20. The test subjects were to be the age above 20 to obtain a unique and relevant result for current and future referencing. It is there true to state that this research was, in essence, trying to close a scientific gap that was not yet revealed by other scientists during research. Methodology used in the Research At first, the research was conducted with the help of lactose tolerance test...

digestion (enzyme amylase increases the rate at which starch is broken down to maltose) and blood clotting (enzyme thrombin increases the rate of clotting) (Frey and Hegeman). Q2. The enzyme amylase is produced by the salivary glands (salivary amylase) and in the pancreas (pancreatic amylase). Salivary amylase breaks down starch in the mouth into maltose which is absorbed by the body into the bloodstream. All the carbohydrates in the food cannot be exhaustively digested in the mouth. Pancreatic amylase moves to the small intestines through ducts where it completes the digestion of carbohydrates by breaking them into glucose which is absorbed into the bloodstream. This completes the digestion of...

Digestion of Starch AbstractThe human body consists of tiny living units called cells. These cells carry out various physiological processes that are essential for the survival of those cells; hence the whole body. Among these processes are biochemical reactions that make available nutrients in forms which are readily utilized in the body, i.e. digestion of food. Food consists of various components such as starch, proteins, lipids, minerals, and vitamins. These components are broken down (through digestion) by the cells such that they are readily utilized for various purposes such as providing energy, building up of cellular structures as well as facilitating other physiological functions. Digestion...

digestion and washing away of toxic substances in view of the high-calorie fries, bhajias, and red meat. Skipping meals is not good because I find myself overeating during the next meal. Now that I give some thought to my eating behavior, I believe that I need to change. In spite of my love for meat fillings, fries, and bhajias, my health should come first. Therefore, I need to reduce the intake of these high-calorie foods and increase my vegetable intake. I also need to replace the high calorie and less nutrient food choices with healthier options, such as corn, rice, potatoes, and pasta because they have some fiber. I will choose healthier snacks, such as vegetable salads to avoid skipping meals....

digestion, proteases also serve as hormone-like signaling molecules that control critical pathophysiological processes in the body namely; pain and repair mechanisms, homeostasis and inflammation. Different types of proteases can communicate with the cells by splitting a protease activated receptors (PARs), which is a member of the four-G protein-coupled receptors (Zhao, Matthew and Nigel n.p). PARs manifested by nearly all types of cells regulates the critical psychological and disease-related processes and are now the most frequent target in therapy for primary prevalent diseases. To get more insight into the PARs activation and performance we can consider the relations of thrombin in PAR1, PAR3,...
