What is Cellular Respiration?
Cellular respiration allows organisms to use (release) energy stored in the chemical bonds
of glucose (C6H12O6). The energy in glucose is used to produce ATP.
What is Photosynthesis?
All organisms require energy for their chemical reactions. These reactions may be
involved with reproduction, growth, or other activities. Photosynthetic organisms such as
