Life Depends on Photosynthesis
Photosynthesis produces O2 in our atmosphere and transports sugar as sucrose to nonphotosynthetic cells or stores excess sugar as starch.

- Sucrose transport
- Starch storage
- Oxygen production
- Nonphotosynthetic cells
Glycolysis and Cellular Respiration Overview
Cells obtain energy through glycolysis and cellular respiration to produce ATP using glucose, while fermentation allows glycolysis to continue when oxygen is lacking.
