sunlight
surface area
energy molecules
glucose
Looking at the image, which is a diagram of the 2 reactions of photosynthesis, what should P and Q be labeled as?
Both P and Q are Light Independent Reactions
P: Light Independent Reaction (Calvin)
Q: Light Dependent Reaction
Both P and Q are Light Dependent Reactions
P: Light Dependent Reaction
Q: Light Independent Reaction (Calvin)
Photosynthesis takes like energy and converts it into chemical energy in the form of glucose (C6H12O6). The energy is stored in the chemical (a) between the atoms of glucose.
The Light Dependent Reaction needs (a) to happen.
Where does Light Dependent Reaction take place?
Thylakoids
Stroma
Where does Light Independent Reaction take place?
Thylakoids
Stroma
What happens during photosynthesis? (MULTIPLE SELECT)
Absorbs/reflects light
Converts chemical energy into light energy
Converts light energy into chemical energy
Stores energy in the chemical bonds of sugar
Electrons become excited/energized
The (a) are the home of the light dependent cycle. The (b) is the home of the light independent (Calvin Cycle).
G = (a) , D (pointing to liquid filling it up) = (b) , B = (c) , and contained within the thylakoids is the pigment (d)
