Photosynthesis
- Importance
- Converts solar energy
into chemical energy
- Produces food(glucose)
for plants
- Converts solar energy
into chemical energy
- Other info
- Occurs in chloroplasts
- Only in daylight hours
- Two chemical pathways
- Requires energy from sun
- Occurs in chloroplasts
- First chemical pathway:
Light-dependent reaction
- Occurs in the grana
- 1) Chlorophyll embedded in the thylakoid
membranes have their electron excited by the sun
striking them
- 2)These high energy elcetrons are passed
along a series of carrier molecules and their
energy is used to make ATP from ADP
- 3) Water splits into H and O. O is released as a gas
and the H is picked up by NADP and taken the next
chemical reaction

- Occurs in the grana
- Second chemical pathway:
Light-independent reaction
- Occurs in the stroma and
also known as the Calvin
cycle
- 1) CO2 and H enter a complex
biochemical cycle. As they are
passed around, extensive
rearrangement occurs and glucose
is formed.
- 2) Carbon dioxide and hydrogen
are continuously fed into the
cycle.
- 3) ATP (produced in the previous reaction) is
used to run the cycle
- 3) ATP (produced in the previous reaction) is
used to run the cycle
- 2) Carbon dioxide and hydrogen
are continuously fed into the
cycle.
- Occurs in the stroma and
also known as the Calvin
cycle
- Factors that affect the rate of the process
are: temperature, light intensity and
carbon dioxide concentration
