Question

I'M JUST ASKING IF THIS IS CORRECT!!!!
1.You are a curious carbon atom. What type of vegetation would you like to go into? [grass, tree, or plant] List your choice here: _tree_
2.How will you enter the vegetation? _root_ [leaf or root] Hint: Only one of these choices is correct. Since you are a carbon atom, you are part of a gaseous molecule, and gas can only enter vegetation one way.
3. If you enter that way, you are part of the _water_[carbon dioxide or water] molecule. Hint: Water only has and two hydrogen atoms and one oxygen atom (H2O).

Answer 1

4. Once you’re in the leaf, you will travel to the _______chloroplast______ [chloroplast or mitochondria]. Hint: Where does photosynthesis take place?

5. Here you learn that the process of photosynthesis is a series of reactions. The __light dependent___________ [light dependent or light independent] reactions trap energy from sunlight to form ATP and NADPH molecules, giving off _________hydrogen____ [oxygen or hydrogen] gas. Hint: See page 2 of the 2.06 lesson if you need help!

6. You then learn that the _______light independent______ [light dependent or light independent] reactions use the chemical energy and carbon dioxide (that’s you!) to build stable long-term energy storage molecules like glucose and other carbohydrates. Just before you (the carbon atom) are transformed into glucose, someone mentions to you that light independent reactions are also known as the ___Krebs Cycle__________ [Calvin cycle or Krebs cycle].

7. You have now been through the entire process of photosynthesis! That’s quite a feat for a humble little carbon atom like yourself! Let’s review what just happened in the process of photosynthesis. The 3 reactants (the things that must enter the vegetation) are: __________water___ Hint: Your choice in #3, water, and sun energy. The 2 products that are made during photosynthesis are oxygen and ___glucose__________ Hint: What you are transformed into in #6?

Answer 2

8. You’ve had a long day, but it’s not over yet. You are now one of the 6 carbon atoms in a glucose molecule (the chemical formula for glucose includes carbon, hydrogen, and oxygen: C6H12O6). As part of this glucose molecule, you will ______remain stored in the plant_______ [remain stored in the plant or be released into the atmosphere] Hint: Only one of these choices is correct.


Cellular Respiration

9. The second half of your journey is about to begin! What type of animal eats the vegetation you selected in #1? List your choice here: _____woodchucks________

10. As the animal gobbles up the vegetation, you (the carbon atom in the glucose molecule) travel to the _________cytoplasm____ [cytoplasm or ribosome] of the animal’s cell. You find out that this first step of cellular respiration is called glycolysis. Glycolysis is _______aerobic______ [anaerobic or aerobic] which means it does not need oxygen. Hint: See page 2 of the 2.05 lesson if you need help!

11. Your visit to the cytoplasm is short; because you now find yourself being rushed to the ______mitochondrion_______ [mitochondrion or nucleus] where the Krebs cycle takes place (this process is ______anaerobic_______ [anaerobic or aerobic] which means it does need oxygen). Another carbon atom leans over to explain that glycolysis and the Krebs cycle are responsible for breaking down organic molecules (like the glucose you are part of). These stages produce ATP energy molecules and donate high-energy electrons that are important for the 3rd stage of cellular respiration. Hint: See page 2 of the 2.05 lesson if you need help!

12. You are sad to find out that you will not get to experience the 3rd stage of cellular respiration known as the ________electron transport chain_____ [electron transport chain or ionic transport rope]. In this stage (which also requires oxygen), the high-energy electrons of the first two stages assist in the production of more _____ATP________ [water or ATP]. This is where most of ATP molecules are formed for the cell. At the end of the electron transport chain, electrons, hydrogen ions, and oxygen bond together to form ________ATP_____ [water or ATP] molecules. Hint: See page 3 of the 2.05 lesson if you need help…and click the tab that says: Products.

13. But alas, you (a carbon atom) do not go through the electron transport chain. Your journey through the animal’s cell is complete after glycolysis and the Krebs cycle break down the glucose molecule you are part of. You are shocked to discover that after a very long and tiring day, you have once again been transformed. You now find yourself right back where you started—as a cute little carbon atom who is part of a ______water_______ molecule. Hint: What type of molecule did you begin as in #3? The animal exhales and releases you into the atmosphere—so that you can be absorbed by some other type of vegetation…and the journey will begin again!
