Light Phase Flashcards
1
Q
where does the light phase occur
A
in the chlorophyll-containing thylakoids of the grana
2
Q
what activates chlorophyll
A
light
3
Q
what happens to the energy received by chlorophyll
A
the energy received by chlorophyll is taken up by energy carriers
4
Q
what is the first part of energy used for
A
some of the energy is used to split water into hydrogen and oxygen (a process known as photolysis)
5
Q
what happens to the products of photolysis
A
- the oxygen is released into the atmosphere
- the hydrogen is given to an energy carrier compound, NADP which now forms NADPH, and is used in the next phase of photosynthesis
6
Q
what is the other part of the energy used for
A
some of the energy is used to add a phosphate to ADP to form ATP, a high energy carrier
