begins with the absorption of light energy by chlorophyll and other pigments within the thylakoid membranes of chloroplasts This light energy is converted into chemical energy in the form of ATP adenosine triphosphate and NADPH This initial phase the light dependent reactions can be visually represented as follows Insert Figure 1 Diagram of a chloroplast highlighting thylakoid membranes and electron transport chain This process involves a series of electron transport chains Water molecules are split releasing electrons protons H and oxygen as a byproduct The electrons energized by light travel down the electron transport chain generating a proton gradient across the thylakoid membrane This gradient drives ATP synthase an enzyme that synthesizes ATP from ADP adenosine diphosphate and inorganic phosphate Simultaneously NADP is reduced to NADPH carrying highenergy electrons for use in the subsequent stage Key factors influencing lightdependent reactions Light intensity Increased
