1. Describe the movement of molecules
2. Understand the vital role of ATP in all living things
3. Identify and describe the major locations and events of cellular respiration and explain how ATP is made during cellular respiration

A process where molecules tend to move from an area of higher concentration to an area of lower concentration

Passive Transport higher concentration lower concentration
Active Transport
Which one do you think requires energy?

Where does the energy come from?

Ultimately, the source of energy is the sun

However, cells can’t use the sun for power. But cells CAN use ATP

- The energy currency of the cell
- A molecule packed with energy that the cell can use to power various functions
- A rechargeable “battery” that all cells use for energy
