ATP

ATP

• Energy molecule• Used to power all cell activities

What does the cell do with the leftovers?

Biosynthesis

Biosynthesis

• Organic molecules that have been broken down are used to build other organic molecules

Biosynthesis

• Organic molecules that have been broken down are used to build other organic molecules

– Proteins– Lipids– Carbohydrates– Nucleic Acids

Metabolism

• What is metabolism?• How is cellular respiration a metabolic

process?

Metabolism

• Metabolism is the breakdown and buildup of molecules in living things

Metabolism

• Metabolism is the breakdown and buildup of molecules in living things

• Cellular Respiration breaks down organic molecules to release energy, and then synthesizes new compounds.
