to which substance does ferredoxin transfer an electron?\nphotosystem i\nphotosystem ii\nnadp+\nnadph
Answer
Brief Explanations:
In the light - reactions of photosynthesis, ferredoxin transfers an electron to $NADP^{+}$ to form $NADPH$. Ferredoxin is the last electron carrier in the electron - transport chain of the light reactions. Photosystem I and II are involved in the initial steps of the electron - transport chain and do not receive electrons from ferredoxin. $NADPH$ is the reduced form of $NADP^{+}$ and is the product of the electron transfer from ferredoxin to $NADP^{+}$.
Answer:
C. $NADP^{+}$
