Name the characteristics found in
carbohydrates.





Carbon
Hydrogen
Oxygen
Ratio is 1 Carbon : 2 Hydrogen : 1 Oxygen
The large molecules can be broken down into
smaller that are exactly alike.
Name the characteristics found in proteins


Made of carbon, hydrogen, oxygen and
nitrogen
Has a globular shape
Name the characteristics of


Contains elements Carbon, hydrogen, and
oxygen
Contains polar molecules that are insoluble in
water
Name the characteristics of nucleic acids

Two main types
RNA and DNA


Contain hereditary code for proteins
Contains oxygens, carbons, and nitrogens
What is a covalent bond?

When two atoms share an electron equally to
make a bond.
What is an ionic bond?


When one atom (Na) gives another atom (Cl)
and outershell electron.
Na then becomes positive and Cl becomes
negative.
Know the atomic particles and their
charges

Protons
Positive, found in the nucleus

Neutrons
No charge, found in the nucleus

Electrons
Negative, found outside the nucleus in orbitals
True or False: Carbon atoms can be found
in inorganic compounds.


FALSE
Carbon can be branched, straight chained or
circular.
Why are enzymes important?


Enzymes are proteins that speed up internal
processes.
Without enzymes processes would take too
long to sustain life.
What polymer does the monomer
nucleotides make?

Nucleic Acid
What are lipids made of?

Fatty acids.
Name some examples of lipids.




Any oil
Vegetable oil
Olive oil
Canola oil
What does non polar mean? Which
polymer is non polar?


Non polar means it can not combine with
water
Lipids are non polar
Which molecule is a sugar?
Molecule 1
Organic molecules all contain what
element?

CARBON
Why is Carbon the center of all organic
compounds?

Because it can combine with four different
elements at a time.
Energy is found in two forms…what are
they?


ADP
ATP
What do animals store carbohydrates as?

glycogen
What form do plants store carbohydrates
in?

cellulose
What is another name for carbohydrates?

polysacharrides
Many amino acids make up what polymer?

protein
