11. Contrast saturated and unsaturated fats – how does this relate to the concept that structure
and function are linked?
12. Label the molecule on the right.
13. List the eight categories of proteins
and their basic function.

17. What are the roles of nucleic acids?
18. Label the diagram to the
right:
19. What is meant by “DNA is
antiparallel”?
BIG IDEA: We are all built from the
same basic building blocks, yet are
so different. How?
