Energy and the Laws of Thermodynamics (emphasis on light to chemical energy transformations) 400 2. Photosynthetic system (chloroplast structure/function) 400 3. General equation (recognize reactants and products) 400 4. Two sets of reactions with emphasis on reactants and products for each set 400 5. Cell respiratory system (mitochondria structure/function) 400 6. General equation (recognize reactants and products) 400 7. Two sets of reactions with emphasis on the reactants and products for each set; special attention to ATP production 400 8. Respiratory process may include an alternative pathway called fermentation 400 400 500 Students will develop an ability to: 500 1. Recognize the significance of energy storage within chemical bonds for living systems, 500 2. Identify reactants/products of photosynthesis, 500 3. Develop the logic of light E to chemical E conversion within photosythesis, 500 4. Note the role of light, water, and carbon dioxide in the photosynthetic process, 500 5. Identify reactants/products of cellular respiration, 500 6. Develop the logic of converting food (glucose) chem. bond energy into the readily available chemical energy of ATP, 500 7.
