Terminology: use your
understanding of prefixes and root
words to make sense of the
following:

Monomers: (mono- one) – this is the term we use to call the general
building blocks of each biomolecule.

Polymers: (poly- many)- this is a general term we use to indicate the
chain of monomers strung together

Dehydration synthesis: dehydration (de-without) (hydro- water)
(synthesis- building)- this is the term used to explain the process of
building of polymers from monomer units by taking away water.

Hydrolysis: (hydro- water) (lysis- breaks apart)- this is the term used to
explain the process of breaking down polymers into monomers by
adding water.

Activity: Biomolecules
Carbohydrates, Lipids, Proteins & Nucleic
Acids
DO NOW: What do you know about:
-
Carbohydrates
-
Lipids
-
Proteins
-
Nucleic Acids
-
All of these are ORGANIC. What does that mean?
-
Are they living or nonliving? How do you know (what are the characteristics
of life)?
-
What role do they have in the body?
-
Why do you think they are considered biomolecules?
-
What do they look like? (Structurally) and how is their structure related to
their function?
ORGANIC BIOMOLECULES
& Living/Nonliving

Organic means: THEY CONTAIN CARBON.

AND THEY ARE CONSIDERED…….NONLIVING
WHY?????
Because they don’t show all characteristics of life:
-
Cells
- growth
- reproduction
-
Evolve
- reponse to stimuli
- heredity (DNA/RNA)
- homeostasis
