The phase of photosynthesis that converts light energy into ATP and NADPH.

The process of dividing water into protons, oxygen, and electrons during photosynthesis.

The byproduct of splitting water in the light reactions, resulting in O2.

The movement of excited electrons through a series of proteins during photosynthesis.

The initial protein complex in the light reactions that absorbs light to excite electrons.

The protein complex that captures light energy and reduces NADP+ to NADPH.

The path of electron transfer in light reactions that produces NADPH, depicted as a zigzag.

The creation of NADPH from NADP+ as a result of electron transfer during photosynthesis.
