WebThe rate of photosynthesis increases sharply. Describe the electron transfer pathway from photosystem II to photosystem I in the light-dependent reactions. After splitting water in PS-II, high energy electrons are delivered through the chloroplast electron transport chain to PS-I. WebCarbon dioxide is consumed during photosynthesis, and the carbon is incorporated in the phytoplankton, just as carbon is stored in the wood and leaves of a tree. Most of the carbon is returned to near-surface waters when phytoplankton are eaten or decompose, but some falls into the ocean depths.
