Photosynthesis Cornell Note Hints
• When drawing diagrams put labels on left side and drawing on right
• Text in Bold – Put on the left side• Text next to or below bold – put on right side• EX:
– ELECTRON (ENERGY) CARRIERS:Molecules that transport energy from one molecule to another
Electron Carriers
Molecules move NRG from one mole. to another

Remember…Chloroplasts in Elodea
Look Inside a Chloroplast*Draw a chloroplast and Label the Thylakoids and Stroma (liquid portion of chloroplast)
ELECTRON (ENERGY) CARRIERS:Molecules that transport energy from
one molecule to another
Example:
• ATP – ADP adds a phosphate group to
become ATP, a high energy bond.
• NADPH– NADP+ picks up a H+ and stores energy as
NADPH.
Photosynthesis is actually a TWO STAGE Process
1) Light energy from the sun is converted into energy carriers ATP and NADPH and Oxygen is released. Note: Water makes O2
2) The energy from ATP and NADPH is used to make SUGARS from Carbon Dioxide.

Overall Photosynthesis ReactionDraw and Label
Copyright Pearson Education, Inc., Publishing as Benjamin Cummings
Step A: Light-Dependent Reaction
• Occurs in the Thylakoid Membrane.
• Light Energy from the Sun:– Splits water producing
Oxygen Gas– Converts ADP into ATP
and NADP+ into NADPH.
Light dependant reaction animation
Step B: Light-Independent Reaction (Calvin Cycle)
• Occurs in the Stroma• ATP and NADPH
from the Light Reaction are used to produce high-energy sugars such as glucose.
