Relate producers to photosynthesis
Describe the process of photosynthesis

a process that captures energy from the sunlight to make sugars that store chemical energy

To capture energy
◦ Sunlight  ATP
Make glucose (sugar)

Organelle: Chloroplast
Structures Inside a
Chloroplast
(write under notes)
◦ Thylakoids: saclike photosynthetic membranes in chloroplast
◦ Grana (granum): stacks of thylakoids
◦ Stroma- region outside thylakoid membrane
Chlorophyll: a molecule that absorbs some of the energy in visible light

2 Cycles in Photosynthesis
◦ 4a) Light Dependent Reaction
 Produces ATP
◦ 4b) Light Independent -Calvin Cycle
 Uses ATP from Light Reaction
 Creates Sugar from Carbon dioxide




Location: Takes place in grana/thylakoid
Reactants: H20 and energy from light
Products: oxygen gas
Goal: convert ADP and NADP into the energy carriers ATP and NADPH (carries electrons for energy) for light independent reactions
4a) Light-Dependent Reactions





No light required
Location: Stroma
Reactants:
◦ ATP and NADPH created in the light dependent reactions
◦ Uses CO2
Products: high energy sugars (glucose
4b) Light-Independent Reactions
 “Calvin Cycle”

Draw this picture in your notebook 


Amount of water in the environment
◦ shortage can slow/stop photosynthesis
5) Factors Affecting
Photosynthesis


Temperature
◦ Between 0-35C degrees is ideal
5) Factors Affecting
Photosynthesis


Light intensity
◦ Increase light will increase in photosynthesis until max rate is reached
5) Factors Affecting
Photosynthesis
