BIOS256 OL, Week 1 Lab Name: Joyce Franco-Thompson OL Lab 1: Carbohydrates: The sugars that feed us Learning Objectives : Understand the molecular structure of sugars and polysaccharides Understand digestion and appreciate the complexity of the human body Experiment with different foods and measure their impact on the blood sugar level Since carbohydrates are the preferred source of energy, these are an essential part of our diet. Grains, fruits, and vegetables are natural sources of both soluble and insoluble carbohydrates. The insoluble part is known as fiber, which is mostly cellulose. In this simulation, you will learn how carbohydrates are digested and learn how different food types affect blood glucose levels in a virtual test subject. An in-lab molecule visualizer will help you to study the chemical structure of sugars and learn the basics of molecule structures and chemical formulas. You will perform a real experiment to understand the action of amylase on starch. Will you be able to use the data from the simulation to figure out how foods can affect blood sugar levels in the body? Part 1: Complete Labster- Carbohydrates: The sugars that feed us Part 2: Report and Reflection Purpose: Describe in your own words and in complete sentences, the purpose of this experiment. The goal of this activity is to learn how your body takes carbohydrates in terms of molecules that are eaten and broken down into glucose that is stored and used. Observations: List 2 observations you have made in this simulation. 1. Carbohydrates are compounds of sugar. Carbohydrates are broken down by the organism into glucose. Blood sugar, or glucose, is the primary energy source for the cells, tissues, and organs of the body. It is impossible for the blood sugar level to fall below 4mM.Regardless of the absence of sustenance in the small intestine, glucose is essential for cellular function.
BIOS256 OL, Week 1 Lab Name: 2. Consuming more carbohydrates, particularly complex carbohydrates, can provide additional energy before a long race. Whole grains, peas, and legumes are all sources of complex carbohydrates. Answer all the questions below: 1. Why should complex carbohydrates be broken down? (1 point) Complex carbohydrates have longer sugar molecule chains than basic carbs. These sugar molecules are converted by the body into glucose, which it needs for energy. Complex carbs take longer to break down and supply more energy in the body than simple carbohydrates since their chains are longer. 2. Where does the absorption of glucose occur in the GI tract? (1 point) Absorption of glucose takes place in the small intestine. 3. What are the anatomical features of the stomach that support digestion? (2 points) The anatomical characteristics consist of the fundus, body, cardia, and pylorus.
BIOS256 OL, Week 1 Lab Name: 4. List out 3 hormones that are secreted by the stomach, the target organ and the action. (6 points) 1. Gastrin stimulates stomach acid output and gastric epithelial growth. 2. Secretin stimulates pancreatic and biliary production of water and bicarbonate. 3. Cholecystokinin stimulates pancreatic enzyme secretion as well as gall bladder contraction and emptying. 5. Reflection: Reflect on at least 2 key concepts you have learned from this simulation. How can you apply it to the physiological processes in the body? Blood sugar levels are affected by how many carbs you eat. Blood sugar levels can go up if you eat a lot of carbs. Hyperglycemia, which means "high blood sugar," can make you more likely to get diabetes. When you start to eat certain things, digestion begins. Starch and glycogen are broken down into simple sugars by an enzyme called amylase, which is found in saliva. As the test went on, I tried some bread. The more I chewed it, the sweeter it tasted.
