A membrane-bound organelle in green plant and algal cells that carries out photosynthesis.
The protein-rich semiliquid material in the interior of a chloroplast.
A disk-shaped sac in the stroma of a chloroplast.
Stacks of tylakoids.
Groups of unstacked thylakoids between grana.
The photosynthetic membrane within a chloroplast that contains light gathering pigment molecules and electron transport chains.
A fluid-filled interior space enclosed by the thylakoid membrane.
A molecule containing three high energy phosphate bonds that acts as the primary energy-transferring molecule in a living organism.
A molecule containing two high-energy phosphate bonds that may be formed by breaking one of the phosphate bonds in ATP.
A compound that accepts one hydrogen atom and two electrons forming NADPH; it is an electron acceptor.
A compound that donates one hydrogen aton and two electrons to another molecule, to reform NADP+; it is an electron donor.
reactions of photosynthesis that use energy from light to produce ATP and NADPH
The process of incorporation CO2 into carbohydrate molecules.
A cyclic set of reactions occurring in the stroma of chloroplasts that fixes the carbon of CO2 into carbohydrate molecules and recycles coenzymes.
The second set of reactions in photosynthesis that do not require light.

Electron Transport Chain
A series of progressively stronger electron acceptors; each time an electron is transferred, energy is released.
A chemical reaction in which a compound is broken down by light.
A reaction in which an atom or molecule loses electrons.
A reaction which an atom or molecule gains electrons.
A process for synthesizing ATP using the energy of an electrochemical gradient and the ATP synthase enzyme.
