The electrons flowing through the electron transport chains in photosynthesis originate from ____ and are transported to the carbon reactions by _____.

Question

Quizplus · Accepted Answer

The electrons flowing through the electron transport chains in photosynthesis originate from water molecules and are transported to the carbon reactions (also known as the Calvin cycle) by NADPH. This electron transport chain is part of the light-dependent reactions of photosynthesis. Oxygen is not involved in the electron transport chain and is instead produced as a byproduct of water splitting during photosynthesis.
