The wavelength (color of light) reflected most by chlorophyll
Molecule that gets split by sunlight's energy during the light-dependent reactions
Molecules that speed up chemical reactions
The chemical process that breaks down glucose to release ATP
The major organic compound produced during photosynthesis
The process of converting light energy into chemical energy
One of the two high energy compounds produced during the light-dependent reactions
Photosynthetic membranes that contain the chlorophyll pigments
A stack of thylakoids
Place in a chloroplast where the light-independent reactions occur
Number of carbon (C) atoms in 1 molecule of glucose
The five-carbon molecule that is the starting & ending compound for the Calvin cycle
A waste product that gets excreted (released) during the light-dependent reactions
DIRECTIONS
In the space below, write the overall chemical equation for photosynthesis:
Using the space below, draw a gigantic chloroplast that is very detailed. Please use
colored pencils for the sketch. Label the following structures:
outer membrane, inner membrane, thylakoid, grana, stroma, chlorophyll
Using the outer margins in your diagram above, EXPLAIN what is occurring in the
GRANA during the light-dependent reactions AND what is occurring in the
STROMA during the light-independent reactions (Calvin Cycle).
Please be very specific in your responses.
Chemical equations may help in your explanations.
