4. Ingredients:
1. Oxygen (O2)
2. Glucose (C6H12O6)

5. Oxygen enters through the process of…
Oxygen enters the cell through the process of diffusion, which is the movement of molecules from high to low concentration.
When you breathe in, there is a higher concentration of oxygen located outside your cells than inside.
Therefore, the oxygen diffuses into the cell.

6. Oxygen diffuses into our red blood cells

7. Glucose enters a cell through the process of…
Glucose enters a cell through the process of active transport, which is the movement of molecules from low to high concentration.
Your cells never want glucose to leave a cell.
The extra glucose inside the cell will be stored for later use.

10. Product:
1. Carbon Dioxide (CO2)

11. C02 exits a cell through the process of…
CO2 is transported out of a cell by the process of diffusion.
After cellular respiration, there is a higher concentration of C02 on the inside than outside of the cell
Therefore, the extra C02 diffuses out of the cell

13. Making Connections
Directions: Using information in this PowerPoint, write the following:
1. A description of cellular respiration
2. Explain how diffusion, active transport and cellular respiration are connected
