1. DO NOW:
Based on the summary equation for photosynthesis shown below, which of the following is produced by the reaction? Why do you say that?
6CO2 + 6H2O + light → C6H12O6 + 6O2
A CO2
B H2O
C light
D C6H12O6

2. How do plants convert the sun’s energy to sugar?
Photosynthesis
How do plants convert the sun’s energy to sugar?

3. Three Step Process
Photosynthesis is the basic process of turning Carbon Dioxide and water into Sugar and oxygen
There are three steps:
Collect the suns rays
Make energy carrying molecules (NADPH + ATP)
Make Glucose (sugar) in the Calvin Cycle

7. Step 1 Collect light
The light collecting is called the light reactions.
Sun rays hit the leaves top layer and enter through to the palisades layer.
In the palisades layer there are hundreds of chloroplasts.
Inside each chloroplast is a thylakoid where water is waiting to be split and used for energy and hydrogen.

9. Step 2: Making of ATP and NADPH
ATP (Adenosine TriPhosphate)
made from ADP+Phosphate+the energy from the split of water.
NADPH (Nicotinamide Adenine Dinucleotide
Phosphate)
- is made from NADP+ and a Hydrogen
from the split of water.

10. NADP NADPH

11. ADP
ATP

12. Step 3: Calvin Cycle making Glucose
The ATP and NADPH is used to run the Calvin Cycle and eventually make C6H12O6
The cycle turns 6 times Using 1 CO2 for each turn.
The final product of Photosynthesis and the Calvin cycle in 1 molecule of Glucose.

13. Glucose
