Study Guide: Digestion and Biological Molecules
To-Do Date: Jan 25 at 9:30amIn order to understand diabetes, we need to think about our food and our bodies both at the large scale (organs like our stomach or pancreas) but also on increasingly smaller scales ( like the molecules that make up our food, or the cells that make up our organs). Here is a flowchart that helps me to organize my thinking on the subject. This week we are going to focus on the first parts of this flowchart: Food--> Digestive System --> Subunits--> Absorbed
Study Guide Questions: Here is an outline of what you need to learn this week.
1. Biological Molecules: be able to fill in this chart:
| Macromolecule | Examples | Monomer/subunit | What do we do with either the macromolecule or subunit? | What is an example of a food that is rich in this type of macromolecule or subunit? |
|---|---|---|---|---|
| Carbohydrates | ||||
| Lipids | ||||
| Proteins | ||||
| Nucleic Acids |
2. Digestive System: What are each of the following processes? Which parts of the digestive system are used for each of them? (note, more than one organ participates. For example, digestion happens a bit in the mouth but mostly in the....).
-
-
-
- Digestion
- Absorption
- Elimination
-
-
3. What are digestive enzymes? Why must they be present and functional in order for absorption to take place? Where are they produced? Where are they active?
4. Why is a high surface area to volume ratio crucial for the small intestine? What gives the small intestine such a high surface area to volume ratio (more than one answer)?
Unit Assessment Questions:
At the end of the Diabetes Unit, you will need to turn in answers to the Unit Assessment Questions. There will be 2-3 of these questions per week, for a total of ~ 10 questions on Diabetes. As mentioned before, you are welcome to use your book, notes AND you may work on it with anyone you would like - myself, fellow student, tutor, etc. BUT, your answers MUST be in your own words.
D1. When you eat a vegetarian burrito that is filled with beans, rice and cheese. Describe what happens to the food in each organ of your digestive system.. Make sure to use the following vocabulary: protein, carbohydrate, lipid, amino acid, sugars, fatty acids, digestive enzymes, liquifying, cell membranes.
