Photosynthesis
* End products: Glucose (C6H12O6) and Oxygen (O2)
* Glucose is a sugar that serves as the primary energy source for cells.
* Oxygen is released as a byproduct and is essential for respiration in most organisms.
Cellular Respiration
* End products: Carbon Dioxide (CO2), Water (H2O), and ATP (adenosine triphosphate)
* Carbon dioxide is a waste product that is exhaled.
* Water is also a waste product.
* ATP is the primary energy currency of cells. It is used to power various cellular processes.
Key Relationship:
Notice the beautiful connection between these two processes: The products of one are the reactants of the other!
* Photosynthesis: Uses CO2 and H2O to create glucose and O2.
* Cellular Respiration: Uses glucose and O2 to create CO2, H2O, and ATP.
This cycle demonstrates how organisms use energy from sunlight to create energy-rich molecules (glucose) and then break them down to release usable energy (ATP) for their activities.
