4. Recognize the components of an ADP and ATP molecule (refer to your packet).

5. Be able to explain how energy is released from ATP, what happens to release the energy?

6. Why do living things need both glucose and ATP as sources of energy? Explain in detail.

7. Known the equations for both photosynthesis and cellular respiration.

Photosynthesis:

Ruben-Kamen photosynthetic equation:

Organelle it happens in: _________________________________

Stores energy Releases energy (Circle one)

Cellular Respiration:

Organelle it happens in: _________________________________

Stores energy Releases energy (Circle one)
