Photosynthesis

Light dependent stage

• where: in the grana of chloroplasts

• H2O is split to produce H+ and O2 molecules

• The O2 is released into the environment (is a by - product) and the H+ ions are picked up by NADP molecules & transported to the stroma

• 2 ATP molecules are also produced which moves the stroma

Light independent stage

• Occurs in the stroma of the chloroplast

• The energy from ATP → used to combine C02 w/t H+ ions dropped off by the NADP(H) → this is known as carbon fixing (& the Calvin cycle)

• C6H12O6 (glucose is produced)

Inputs and output of the light dependent stage

Inputs - H2O, ADP + Pi, NADP+

Outputs - O2, ATP, NADPH

Inputs and output of the light independent stage

Inputs - ATP, NADPH, CO2

Output- ADP + Pi, NADP+, glucose
