Digestion and Leaky Gut Why is Digestion Important? Healthy digestion is crucial for health and wellbeing. Everything we ingest has a purpose, either it will nourish the body and act as fuel or will lead to various health conditions, some can be minor but while some lead to chronic disease. If our digestive system is not working properly, even with the best diet, nutrient absorption will be reduced. A huge function of digestion is to breakdown food, reducing it basic nutrients to be used as…

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation, scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites, ensuring that all DNA fragments that contain a particular sequence have the…

body. You might find yourself asking, what does blood have to do with digestion, respiration and circulation? Hopefully, after the presentation all of your questions will be answered. When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First, Mastication begins. Mastication is the chewing of the food…

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab, I will study how digestion of carbohydrates, proteins, and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical…

Our bodies break down starch into the individual glucose units, which are further metabolized into CO2 and water through the process of glycolysis—this is the process we commonly call digestion. The enzyme amylase is present in our saliva and begins the process of digestion when starch containing foods enter our mouths. In this lab you will measure the amount of amylase present in your saliva by monitoring the breakdown of starch. Introduction: You can probably name a variety of foods that are referred to as “starchy”…

LABORATORY REPORT Activity: Effect of Dietary Fiber on Transit Time and Bile Name: Hope Schallert Instructor: Dr. Weithop Date: 03.08.2015 Predictions Dietary fiber will: increase transit time Dietary fiber will increase the amount of bile acid in solution Materials and Methods Effect of Dietary Fiber on Transit Time 1. Dependent variable. number of radiopaque markers in GI tract 2. Independent variable. amount and type of fiber in meal 3. Controlled variables. calories in meal, nutrients…

Week 7 Digestion Lecture Study Guide Based on information found in the lecture folder or other sources, answer the following questions. 1. What is digestion? Digestion is the mechanical and chemical breakdown of food into usable molecules 2. List some other names of the digestive tract. Alimentary Canal (GI Tract) 3. Explain where and how the mechanical breakdown of food occurs. Teeth begin digestion mechanically, Chewing (“mastication”) breaks apart food, 2 sets…

enzymes? What specifically is the role of an enzyme in digestion? Enzymes are working proteins that facilitate chemical reactions without being changed in the process. Organs of the digestive system excrete digestive juices, which contain enzymes that break the bonds of nutrients that can be absorbed. 2. Trace the path of a cheeseburger and fries through the digestive tract. Indicate each place where mechanical digestion, chemical digestion, and absorption occurs FOR EACH NUTRIENT (carbohydrates…

Gastrin is released primarily in response to protein in the stomach, and its effects promote digestion of protein. Secretin is released in response to acid in the duodenum, and its effects will neutralize the acid. CCK is released in response to fat in the duodenum, and its effects optimize conditions for fat digestion reactions. (Sherwood, 2013) Digestion of carbohydrates begins in the mouth (salivary digestion), where the salivary glands (submandular, sublingual or parotid) will secrete an amylase…

The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry, those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper, chemistry can be seen everywhere. However, most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread, once consumed, can turn into fuel for the human…
