carbon dioxide, water
What are the products that a student could count to calculate the rate of photosynthesis?
oxygen
When does photosynthesis occur? Explain why.
Photosynthesis occurs when conditions are right - light, pH, temp, etc. - because these factors are necessary for the process of photosynthesis to take place.

Study Notes
Photosynthesis
- To produce glucose during photosynthesis, the reactants needed are light, water (H2O), and carbon dioxide (CO2).
- The products that can be counted to calculate the rate of photosynthesis are oxygen (O2) and glucose (C6H12O6).
When Photosynthesis Occurs
- Photosynthesis occurs in the presence of light, typically during the daytime.
Glucose Breakdown
- Glucose is broken down in a process called cellular respiration.
- The matter within the glucose is conserved through this process because it produces carbon dioxide (CO2) and water (H2O).
Respiration Types
- The main difference between aerobic and anaerobic respiration is the presence of oxygen (O2); aerobic respiration uses oxygen, while anaerobic respiration does not.
Fermentation Types
- The two main differences between alcoholic fermentation and lactic acid fermentation are:
- The end products: ethanol (C2H5OH) and carbon dioxide (CO2) in alcoholic fermentation, and lactic acid (C3H6O3) in lactic acid fermentation.
- The location: alcoholic fermentation occurs in yeast, while lactic acid fermentation occurs in muscle cells.
Anaerobic Respiration Steps
- The steps in anaerobic respiration are:
- Glycolysis
- Fermentation (either alcoholic or lactic acid)
Factors Determining Respiration Type
- The two primary factors that determine what type of respiration a cell will undergo are:
- The presence or absence of oxygen (O2)
- The type of cell or organism
