1. Photosynthesis Chapter 8 in the Textbook

2. Chemical Energy and ATP What type of organic macromolecule is shown in the diagram? The in the diagram label the following: – Phosphate groups – Sugar – Nitrogenous Base

3. ATP (adenosine triphosphate) is the most important molecule cells use to store and release energy Energy: the ability to do work Energy comes in many different forms: Light energy Mechanical Energy Chemical Energy Chemical Energy and ATP

4. – Where do YOUR cells get the energy to convert ADP into ATP? – How is ATP and ADP similar to rechargeable batteries? When an organism uses the energy from ATP, the ATP is converted into ADP – ADP (Adenosine Diphosphate ) has only 2 phosphate groups. – Cells can add a phosphate to ADP to make ATP to store energy. (This requires energy) Chemical Energy and ATP

5. The mitochondria and the chloroplast are the most important organelles in energy transformations. Chloroplast – Uses the energy in sunlight to create glucose – Found in the cells of plants and protists Mitochondria – Uses the energy in glucose to convert ADP into ATP – Found in the cells of all eukaroytic organisms (including plants!!!)
