Levels of Organization Part 3: Biomolecules

• ​Carbohydrates

  • Contain: C, H, O in Rings

  • QUICK Energy

• ​Lipids

  • Contain: C, H, O in Chains

  • STORED Energy

• ​Proteins

  • Contain: C, H, O, N

  • Do Cell Processes (Enzymes)

• ​Nucleic Acids

  • Contain: C, H, O, N, P

  • Store Genetic Information

​Know the big 4!!!!

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)

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
