(b) The first stage of photosynthesis is known as the light stage. It involves energising electrons and moving them along two different pathways. (i) Write a brief description of what happens along both of these pathways. (ii) What happens to the products of the light-dependent stage? (27)

stage is the light-dependent reaction, (see below) during which energy from sunlight is captured and converted to chemical energy, in the form of ATP and NADPH. In this step, water molecules (H 2 O) are broken apart, releasing electrons and hydrogen ions for use in stage two of photosynthesis, and releasing oxygen as a waste gas. Oxygen

Products of the light-dependent stage Both cyclic and non-cyclic photophosphorylation drive the synthesis of ATP, so we know this is one product of the light-dependent stage. The other useful product for photosynthesis is NADPH (reduced NADP), which is an important molecule for the following stage (see 3.3 Light-independent reactions).
