electrons and H+
ATP and NADPH
The light reactions occur in the ________ and the light independent reactions take place in the ________.
Chloroplast / thylakoid membrane
stroma / thylakoid
mesophyll / stomata
thylakoid membrane / stroma
Electron transport helps establish a _____ that powers ATP production.

Where do the electrons in Photosystem I go?
they go to Photosystem II
they get collected by ADP and turn into ATP
they get collected by NADP+ and turn into NADPH
they go to the ATP Synthase
What does light do when it strikes the chlorophyll molecules of photosystems I and II?
Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems.
Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.
Light causes the conversion of water into carbon dioxide, oxygen, and electrons.
Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle.
After light excites the electron and they leave Photosystem II to travel down the first electron transport chain, how are these electrons replaced to Photosystem II?
Oxygen is reduced and the electrons are given to the chlorophyll molecules of photosystem II.
Carbon dioxide is split, and the electrons are given to the chlorophyll molecules of photosystem II.
Hydrogen undergoes fusion, and the electrons are given to the chlorophyll molecules of photosystem II.
Water is split, and the electrons are given to the chlorophyll molecules of photosystem II.
