Question 1
A. What are the monomers (or subunits) of the following four macromolecules?
1.complex carbohydrates (polysaccharides)
2.lipids
3.proteins
4.nucleic acids
B. What type of chemical reaction is responsible for the formation of these complex molecules from their monomers?
C. Consider the structure and function of each of these four biological macromolecules. How does the structure of each molecule affect its function? For example, in complex carbohydrates, why would long chains of glucose be more effective for energy storage than single glucose molecules? How do the four levels of protein structure affect the shape of enzymes and why is this important for enzyme function? Explain the “lock and key” model of enzyme function using the terms substrate, active site, and product.

Question 2
Describe the fluid mosaic model of the cell membrane and then describe how things move through this membrane differently by means of the following six processes:
1.diffusion
2.osmosis
3.facilitated diffusion
4.active transport
5.endocytosis
6.exocytosis

In your answer, be sure to fully explain the differences among the six different types of movement.
Answer each question in two to three well written paragraph and should be one paper.
