Photosynthesis
2
Occurs within the chloroplasts of plant cells, and in daylight hours.

Photosynthesis Occurs within the chloroplasts of plant cells, and in daylight hours. Water and Carbon Dioxide are joined to produce the sugar glucose – oxygen is a waste product.

4
Light-dependent reaction (1 st pathway) Takes place on the thylakoid membranes of the grana of chloroplasts.
5
Light-dependent reaction (1 st pathway) Takes place on the thylakoid membranes of the grana of chloroplasts. Chlorophyll embedded in the thylakoid membrane have their electrons ‘excited’ by solar energy. Takes place on the thylakoid membranes of the grana of chloroplasts.

6
Light-dependent reaction (1 st pathway) Takes place on the thylakoid membranes of the grana of chloroplasts. Chlorophyll embedded in the thylakoid membrane have their electrons ‘excited’ by solar energy. These high-energy electrons are passed along several carrier molecules and their energy is used to make ATP from ADP. Takes place on the thylakoid membranes of the grana of chloroplasts.

Light-dependent reaction (1 st pathway) Water is split into hydrogen and oxygen – oxygen is not required so is released as O2 gas.
9
Light-dependent reaction (1 st pathway) Water is split into hydrogen and oxygen – oxygen is not required so is released as O2 gas. Hydrogen is picked up by carrier molecules (NADP) and taken to the second pathway. Water is split into hydrogen and oxygen – oxygen is not required so is released as O2 gas.

Light-independent reaction (2 nd pathway) Also known as the Calvin cycle and occurs in the liquid matrix of the chloroplast – the stroma.
11
Light-independent reaction (2 nd pathway) Also known as the Calvin cycle and occurs in the liquid matrix of the chloroplast – the stroma. CO2 and H enter a complex cycle and are passed around it. Rearrangement happens and C6H12O6 is formed as the final product. Also known as the Calvin cycle and occurs in the liquid matrix of the chloroplast – the stroma.

Light-independent reaction (2 nd pathway) Also known as the Calvin cycle and occurs in the liquid matrix of the chloroplast – the stroma. CO2 and H enter a complex cycle and are passed around it. Rearrangement happens and C6H12O6 is formed as the final product. The molecules that form the cycle are NOT used up – CO2 and H are continuously fed in. Also known as the Calvin cycle and occurs in the liquid matrix of the chloroplast – the stroma. CO2 and H enter a complex cycle and are passed around it. Rearrangement happens and C6H12O6 is formed as the final product. The molecules that form the cycle are NOT used up – CO2 and H are continuously fed in.
