ATP

Compound used by cells to store and release energy.

Photosynthesis

Process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting light energy into chemical energy.

Pigment

light absorbing molecule used by plants to gather suns energy

Chlorophyll

Principal pigment of plants and other photosynthetic organisms

thylakoid

Photosynthetic membranes found in chloroplasts

Stroma

fluid portion of chloroplasts outside of the thylakoid

NADP+

Carrier molecule that transfers high energy electrons from chlorophyll to other molecules

Light independant reactions

Set of reactions in photosynthesis that do not require light energy from ATP and NADPH is used to build high energy compounds such as sugar

Light dependant reactions

set of reactions to photosynthesis that use energy from light

Photosystem

Cluster of chlorophyll and proteins found in the thylakoids

Electron transport chain

series of electron carrier proteins that shuttle high energy electrons during ATP generating reactions

ATP synthase

an enzyme for the synthesis of ATP consists of a cluster of proteins that span the cell membrane and allow hydrogen ions to pass.

Calvin cycle

light dependant reactions of photosynthesis in which energy from ATP and NADPH is used to build high energy compounds such as sugar
