Levels of Organization Part 3: Biomolecules

​Compare the functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.

Compare the reactants and products of photosynthesis and cellular respiration in terms of energy, energy conversions, and matter.

AND

Identify and investigate the role of enzymes.

​Know the big 4!!!!

Multiple Select

Which biomolecules provide and/or store energy?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

Multiple Choice

Which biomolecules holds our genetic code?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

Enzymes are proteins that do work in the cell.

• Active site attaches to molecules

• The enzyme binds or breaks the molecule apart

• Enzymes speed up reactions

• Enzymes lower the energy needed for reactions.

​

​Enzymes ("-ace's)

Multiple Select

Select all things that enzymes do:

• Break appart or bind molecules

• Lower activation energy needed

• Speed up reactions

Energy is stored and used by binding and breaking carbon molecules.

Energy storage: Photosynthesis!

6H₂O + 6CO₂ + Light --> C₆H₁₂O₆ + 6O₂

Water + Carbon Dioxide + Energy --> Glucose + Oxygen

Energy harvest: Respiration!

C₆H₁₂O₆ + 6O₂ --> 6H₂O + 6CO₂ + ATP

Glucose + Oxygen --> Water + Carbon Dioxide + Energy
