Station 6
Biomolecules
Essential Question- Bell Ringer
• Biomolecules are organic molecules
produced by living organisms. Which
biomolecule is produced during the
process of photosynthesis and used as an
energy source in cellular respiration?
The biomolecule produced during
photosynthesis is glucose, C6H12O6, and it is
used as the energy source in cellular
respiration
Pre-Review Question

in common?
Carbon, Hydrogen and Oxygen

as a primary source of energy?
A. Lipids
B. Carbohydrates
C. Nucleic Acids
D. Proteins

Discuss with your partner
Biomolecules are molecules that
are synthesized by living cells. Why
are biomolecules important?
These molecules control almost
every aspect of life processes.
Discuss with your partner
Most biomolecules are macromolecules. How
do a biomolecule’s size and the number of
bonds it contains affect the amount of energy
that is available?
As the molecule size increases, so does the number chemical
bonds needed to hold the
structure together. These bonds contain energy, which
enables the molecule to perform its functions. The more
energy contained within the molecule, the more work the
structure can do once the energy is released. Energy is
released when the bonds holding the atoms together are
broken.
Discuss with your partner
The station has three different models of each
biomolecule: a 3-D model, a structural formula,
and a chemical formula (mathematical model).
Locate the 3-D model of glucose. Count and
record, in the table below, the number of carbon,
hydrogen, and oxygen atoms represented in the
model.

Station 6. I need to remember..
Sugars, the smallest carbohydrates, serve as fuel.
Lipids store large amounts of energy.
A protein’s function depends on its unique sequence of amino
acids.
Nucleic acids store and transmit hereditary information.
Organic molecules contain carbon–hydrogen bonds and are
produced by organisms.
