Photosynthesis is the process of which plants convert sunlight water and into a 5 base glucose sugar used for food They use their chloroplasts to do this process there are two stages light dependent and light independent Light dependent takes place in the thylakoid within this thylakoid is a small space separating between each one a full stack of thylakoids are called a Granum this is but one part of photosynthesis In this report I will explain in full detail about the process of photosynthesis and what it takes to perform this function LIGHT REACTIONS There are two parts used to convert light energy and water into glucose light reactions and the Calvin cycle The light reactions take in water and split it into two oxygen and take in the hydrogen light reactions take in water and split it into 02 and H CO2 2H2O photons CH2O O2 H2O NADPH is then carried over into the Calvin cycle as shown in this diagram Light absorbed by chlorophyll drives a transfer of electrons and hydrogen from water to an acceptor call NADP Water is split in this process and because of this process oxygen 02 is then released as a by product of light reactions LIght reactions use solar power to reduce NADP to NADPH by adding a pair of electrons to the hydrogen molecule or H Including the NADPH carried over from the light reactions it also transfers ATP Light reactions make ATP using chemiosmosis to power the addition of a phosphate group to ADP created by the Calvin cycle this process is called photophosphorylation
