Fats, Carbs and Proteins
Q: What does the word carbohydrate mean?
A: The carbohydrate simply means it contains carbon and water. The word carbohydrate comes from a combination of a Latin and a Greek word. The Latin word is carbon which means coal or charcoal. The Greek word is hydrate which comes from the word "hydro" and means water.

Q: Can you show why the name carbohydrate was used?
A: The name carbohydrate was used because all carbs are carbon and water. As a matter of fact if you were to heat sugar or starch in a pot, you see the water evaporating and eventually all that will be left would be carbon which is black.
Q: Name some carbohydrates.
A: Carbohydrates can be crackers, bread, cereal, and pasta. They have grains and contain a lot of carbs like flour cornstarch and wheat. They are all sources of carbohydrates.
Q: What is the difference between simple sugar molecules and Complex sugar molecules?
A: A simple sugar molecule is when there is only one molecule but a complex molecule is to of them attached.

Q: In the digestive system,
- Simple sugar molecules are becoming complex sugar molecules.
- Complex sugar molecules are broken down into simple sugar molecules.
- None of the above.
- All of the above.
A: Complex sugar molecules are broken down into simple sugar molecules. Like the experiment we did with the cracker you found out if you chew it for a long time it becomes sweet. It starts as complex sugar molecule and ends as simple sugar molecule.
Q: Why is it important for complex sugar molecules to break down into simple?
A: This process is important because they need to get in through the cell membrane. While complex sugar molecules cannot pass through the cell membrane, simple sugar molecules can.

Q: What happens when simple sugar molecules pass through our cell membrane?
A: When they go through the cell membrane they burn and release energy. This is known as oxidation. Here is what happens, oxygen is chemically combined with the simple sugar molecules causing sugar to release and burn energy.
Q: If carbohydrates are food for energy, do you know of any other food that plays a different role?
A: Another one would be Proteins which are for growth and repair of cells. Vitamins minerals and water play the role of regulation of body.
Q: Give some examples of proteins.
A: Can be meat eggs cheeses and milk. But also things like beans peas nuts and rice. Are good sources of protein.

Q: What are the proteins made of?
A: Proteins are oxygen hydrogen and carbon but contain something else called nitrogen and also sulfur.
Q: Which are more complex proteins or carbohydrates?
A: Proteins mainly because they consist of much larger molecules and over a thousand atoms can be in one protein molecule.
