2. 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

3. Carbon, Hydrogen and Oxygen

Lipids
Carbohydrates
Nucleic Acids
Proteins

5. Pre-Review Question

6. 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.

7. 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.

8. 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.
Type of atom Number present
carbon
oxygen
hydrogen 6 6 6
