1. Simplified Photosynthesis
Biology I

2. Photosynthesis Equation
6CO2 + 6H2O → C6H12O6 + 6O2
Carbon dioxide + water → sugar + oxygen
Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into oxygen and high-energy sugar.

3. Photosynthesis Happens in two parts
Light Reactions- happen in the thylakiod
Dark Reactions or Calvin Cycle- happen in the stroma

4. Light reaction Light hits the chloroplast.
The electrons in that chloroplast become excited.
These electrons move thru the electron transport chain.
Water will split into Hydrogen and Oxygen. (Oxygen will be released)
As that happens, NADP NADPH.
H+ ions are also moving from the stroma into the thylakoid. This make the inside of the thylakoid positive and the outside negative.
H+ ions are also passing thru ATP Synthase ( an enzyme) and changing ADP ATP

5. Light reactions - products
Oxygen- released from the plant ATP- goes into the Calvin Cycle NADPH- goes into the Calvin Cycle

6. Dark Reactions or Calvin Cycle
The ATP and NADPH made during light reaction, along with CO2, will be used to create one glucose molecule.
Product- Glucose

7. Photosynthesis
In plants photosynthesis takes place inside the chloroplasts. (plate)
Chloroplasts contain saclike photosynthetic membranes called thylakoids. This is where the Light Reactions take place. (pancake)
Thylakoids are arranged in stacks known as grana(plural) or granum(singular). (stack or stacks of pancake)
The Calvin cycle or Dark Reaction takes place in the stroma, the region outside the thylakoid membranes. (syrup surrounding the pancakes)
