Question:

light-dependent reactions

Answer:

"Step 1 of Photosynthesis" chlorophyll and other pigments on the thylakoids membranes use absorbed protons from light to break water and excite one of the water's electrons.

Question:

NADPH

Answer:

a type of molecule called an electron career- is adapted to move an electron from one reaction to another

Question:

Calvin Cycle

Answer:

"Step 2 of Photosynthesis"(light-independent reactions) occurs in the storm of chloroplast. The plant uses the energy from ATP and the electron from NADPH to build sugars out of CO2.
