4.3 photosynthesis in detail

function of light dependent reactions

to capture and transfer energy

photosystems

two groups of molecules that capture and transfer energu on the thylakoid membrane

function of calvin cycle

to make simle sugars

electron transport chain

series of proteins in membrane of thylakoid

three parts of light-dependent reactions

photosystem 2, photosystem 1, atp synthase

functions of photosystem 2

transfers energy to electrons that travel through series of proteins called electron transport chain, water molecules broken down, hydrogen ions pumped across thylakoid membrane

functions of photosystem 1

additional energy absorbed from sunlight and transferred to electrons in electron transport chain, used to produce nadph

function of atp synthase

hydrogen ions flow through atp synthase that produces atp and transferred to light independent reactions
