- Photosynthesis
- Light dependent stage
- Light hits chlorophyll
- Electrons excited and raised to higher energy level
- Pass down electron transport chain losing energy
- This energy used to make ATP from ADP and Pi
- H2O splits into H+, e- and O. e- replace those lost in chlorophyll, O useful waste product
- Process occurs again but electron from chain and H+ from photolysis reduces NAD
- H2O splits into H+, e- and O. e- replace those lost in chlorophyll, O useful waste product
- This energy used to make ATP from ADP and Pi
- Pass down electron transport chain losing energy
- Electrons excited and raised to higher energy level
- Thylakoid
- Light hits chlorophyll
- Light independent stage
- RuBP combines with CO2 to form 2 X GP
- GP reduced to TP this requires reducing power of ATP and NADH2
- Some TP used to make carbohydrates, amino acids, Triglycerides
- Some TP regenerated to RuBP which requires reduction of ATP
- Some TP used to make carbohydrates, amino acids, Triglycerides
- GP reduced to TP this requires reducing power of ATP and NADH2
- Stroma
- RuBP combines with CO2 to form 2 X GP
- Chloroplast adaptations
- Large surface area for attachment of chlorophyll and enzymes
- Stroma has enzymes for light Independent reaction
- Chloroplasts have DNA and ribosomes to make proteins
- Limiting factors
- CO2
- Increase by burning fossil fuels or pumping in CO2, Paraffin heaters
- Light intensity
- Increase by using light or decrease by using blinds to shade plants
- Temperature
- Heaters or paraffin heaters increase temperature
- CO2
- Light dependent stage
