What is the living systems ultimate energy source; or, what is the cell's "energy currency"?
What are the processes by which the photosynthetic mechanism converts light energy into usable chemical energy?
What are the processes by which the cellular respiratory mechanism converts the chemical bond energy of simple sugars into the cell's energy currency, ATP?
What are some of the factors that could affect these energy processes?
1. Energy and the Laws of Thermodynamics (emphasis on light to chemical energy transformations)
2. Photosynthetic system (chloroplast structure/function)
3. General equation (recognize reactants and products)
4. Two sets of reactions with emphasis on reactants and products for each set
5. Cell respiratory system (mitochondria structure/function)
6. General equation (recognize reactants and products)
7. Two sets of reactions with emphasis on the reactants and products for each set; special attention to ATP production
8. Respiratory process may include an alternative pathway called fermentation
Students will develop an ability to:
1. Recognize the significance of energy storage within chemical bonds for living systems,
2. Identify reactants/products of photosynthesis,
3. Develop the logic of light E to chemical E conversion within photosythesis,
4. Note the role of light, water, and carbon dioxide in the photosynthetic process,
5. Identify reactants/products of cellular respiration,
6. Develop the logic of converting food (glucose) chem. bond energy into the readily available chemical energy of ATP,
7. Note the role of oxygen in the respiratory process .
1. Experimentation of factors affecting cellular respiration (pH, temperature, sugar type)
2. Plant pigment analysis
Objective/Subjective testing (50:50 ratio)
Laboratory experiences:
Factors influencing rate of cellular respiration
Food Calorimeter
Cooperative activities
