PART 3 - Complete the chart below. Remember mono means one and poly means many.

Question

MACROMOLECULES FOOD EX. MONOMER POLYMER
Carbohydrates
Lipids
Proteins
Nucleic Acids
Your best friend tells you that they are deathly allergic to certain amino acids in food. Your mom
has prepared dinner already, so you need to tell her not to serve what macromolecule to them?
__________________________________________
PART 4 - Study the image below then answer the questions on the right.
For each example circle whether it is describing dehydration synthesis or digestion and if energy is
needed or released.
1. Which process breaks polymers
into monomers?
2. Which process bonds monomers
into polymers?
3. Which reaction stores energy?
4. Which reaction releases energy?

Answer 1
