Standard III- Photosynthesis and Cellular Respiration

2. Photosynthesis and Cellular Respiration
CONTENT STANDARD III. Identify reactants and products associated with photosynthesis and cellular respiration, and the purposes of these two processes.
ELIGIBLE CONTENT
Identify the chemical formula for photosynthesis.
Identify the function of photosynthesis.
Identify the chemical formula for respiration.
Identify the function of respiration.
Identify the relationship between photosynthesis and respiration.

3. Metabolism Metabolism- All of the chemical reaction s in a cell
Metabolic pathway- Series of chemical reactions in which the product of one reaction is the substrate for the next reaction
Catabolic pathway- Release energy by breaking down large molecules into smaller ones
Anabolic pathway- Use energy released by catabolic pathways to build larger molecules from smaller ones
Relationship between catabolic and anabolic pathways result a continual flow of energy within organisms.

4. Photosynthesis
Photosynthesis- Anabolic pathway in which light energy from the sun is converted to chemical energy for use by the cell
Autotroph/Producer- Organisms that perform photosynthesis
Use light energy, carbon dioxide and water to build molecules of glucose and oxygen
Chlorophyll (green pigment found in chloroplasts) is also required.
Glucose is transferred to other organisms for energy in the form of food.
Occurs in the leaf cells of plants

5. Photosynthesis Sunlight ↓ Chlorophyll 6CO2 + 6H2O ⃗ C6H12O6 + 6O2
Carbon Dioxide Water Glucose Oxygen
Reactants Products

6. Cellular Respiration
Cellular (Aerobic) Respiration- Catabolic pathway in which organic molecules are broken down to release energy for use in the cell
Aerobic- Requires oxygen
Oxygen is used to break down glucose resulting in the production of carbon dioxide and water.
ATP (Adenosine Triphosphate)- Biological molecule of stored energy produced by respiration
Energy is released when the energy storing bond between the second and third phosphate is broken, forming ADP (Adenosine Diphosphate) and a free phosphate group.
Heterotroph- Organisms that can not produce their own food.
Occurs in the mitochondria (powerhouse) of cells.

8. Metabolic Pathway
Photosynthesis and cellular respiration work together to complete a metabolic pathway
The products of photosynthesis are the reactants of cellular respiration and vice versa.
Photosynthesis is necessary to remove energy from the sun, where all energy ultimately comes from.
