Salisbury author. Thus NADPH, ATP, and oxygen are the products of the first phase of photosynthesis called the light reactions. PQH2 passes these to the Cytochrome b6f complex (Cb6f) which uses passage of electrons through it to pump protons into the thylakoid space. Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma but the photosystems and membrane proteins of the electron transport chain are unharmed. So the correct answer here is B and this could be identified by the similarity in their names as they both have phosphor relation in their name. (C) carbon fixation. (ii) Fragmentation: Filaments break into small pieces. In cyclic photophosphorylation, the electrons get expelled by photosystem I and they return to the system. In oxidative phosphorylation, the energy comes from electrons produced by oxidation of biological molecules. Q:Do plant leaves utilise the O2 released during photosynthesis? It is the process of synthesizing energy-rich ATP molecules by transferring the phosphate group into ADP molecule in the presence of light. A: Photophosphorylation is the process of making chemical energy (ATP and NADPH) from light. Energy from ATP and electrons from NADPH are used to reduce CO2 and build sugars, which are the ultimate energy storage directly arising from photosynthesis. Under certain conditions, the photoexcited electrons take an alternative path called cyclic electron flow, which uses photosystem I (P700) but not photosystem II (P680). Carbon is also used to construct the energy-rich molecules adenosine triphosphate (ATP) and guanosine triphosphate (GTP). . Q:Differentiate the cyclic and non- cyclic photophosphorylation.
