Photosystems: complexes of pigments and proteins ( ensymes) that capture light energy and catalyze electron transfer reactions
- antenna pigments absorb light energy - transfer to reaction
Light Reactions
Light energy used to transfer electrons from water to NADP+, forming oxygen gas and NADPH.
Energy released by electron transfer reactions between photosystems (through ETC) used to form Proton Gradient across thylakoid membrane.
Proton gradient used to make ATP via ATP Synthase.
