Macromolecule Jigsaw Instructions:
1. With your pod, research 1 of the
following macromolecules:
proteins, lipids, carbohydrates,
nucleic acids.
2. In foldable (see p. 157) or note
form research the following:
Macromolecule: _____________
 Monomers (building blocks)
 Functions within body
 Where do they come from/how
made?
 Examples
3. Report out. All students will
record additional information.
Proteins:
 Sub-units: amino acids
 Functions: contraction of muscle
tissue, transport O2 in blood,
important in immunity, facilitates all
chemical activity within the body,
structure of cells, tissues and organs
systems.
 Made through protein synthesis- puts
amino acids together to make
proteins in ALL cells.
 Ex’s: enzymes, hair, fingernails,
hooves, skin
Lipids:
 Sub-units: fatty acids and glycerol
group
 Functions: long-term energy
storage, protection, insulative
coverings
 Cells perform lipid synthesis (put
together C, H and glycerol groups
from the nutrients obtained)
 Ex’s: Fats, oils, waxes, steroids
Carbohydrates:
 Composed of saccharides
 Short-term energy, structural
support in plant cell walls,
receptors which aid in cell-cell
communication.
 Comes from primarily plant sources
(potatoes, green plants, fruit),
animal livers produce glycogen.
 Ex’s: wheat, cellulose (plant cell
walls), glucose, fructose,
galactose, starch.
Nucleic Acids:
 Monomers: Carbon, hydrogen,
Oxygen, nitrogen, and phosphorous
( nucleotides)
 Functions: forms DNA, master copy
of an organisms information code,
forms all enzymes,
 Forms RNA, forms a copy of DNA
used for making proteins (protein
synthesis)
 Molecules are passed down through
heredity; then organisms synthesize
more using nutrients available and
replicate during cell division.
 Ex’s: Ribonucleic Acid &
Deoxyribonucleic Acid
