How does the electron transfer pathway from photosynthesis II to photosynthesis I in the light-dependent reactions take place?   A. After splitting water in PS-I, high-energy electrons are delivered through the chloroplast electron transport chain to PS-II.   B. After the photosynthesis reaction, released products like glucose help in the transfer of electrons from PS-II to PS-I.   C. After splitting water in PS-II, high-energy electrons are delivered through the chloroplast electron transport chain to PS-I.   D. After the completion of the light-dependent reactions, the electrons are transferred from PS-II to PS-I.

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
