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.
Observations: List 2 observations you have made in this simulation.
Answer all the questions below:
- Why should complex carbohydrates be broken down? (1 point)
- Where does the absorption of glucose occur in the GI tract? (1 point)
- What are the anatomical features of the stomach that support digestion? (2 points)
- List out 3 hormones that are secreted by the stomach, the target organ and the action.
(6 points)
- 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?
