Compare the similarities and differences between the chemistry of the biomolecules.
You have found carbohydrates in maple syrup, in the tree trunk, and in green leaves. What do they all have in common? What makes them similar and what makes them different from the other groups of macromolecules in a living cell?
How are lipids different from the other three kinds of macromolecules?
In how many places in a cell are those molecules distributed? Take a look at the cell picture. and answer the following questions:
If you needed to collect the nucleic acids of DNA from a cell, where would you go?
Where is the most starch found in the plant cell?
Where do lipids appear primarily in a cell ? What do those places have in common?
Because they are the machines of the cell, proteins are found almost everywhere in the cell. Where are they probably NOT found?
