What is the correct sequence for the following components in photosynthesis as described by the Z scheme?
A)NADPH → P700 → P700* → cytochrome bf complex → P680 → P680* → water.
B)Water → P700 → P700* → cytochrome bf complex → P680* → P680 → NADPH.
C)Water → P680 → P680* → cytochrome bf complex → P700 → P700* → NADPH.
D)Water → P700 → P700* → cytochrome bf complex → P680 → P680* → NADPH.
E)NADPH → P680 → P680* → cytochrome bf complex → P700 → P700* → water.

Question

Quizplus · Accepted Answer

The Z scheme describes the pathway of electron transfer in photosynthesis. The correct sequence of components in photosynthesis as described by the Z scheme is: 
Water → Photosystem II (PSII, P680) → P680* → Cytochrome bf complex → Photosystem I (PSI, P700) → P700* → NADPH.

Option C follows this sequence correctly, whereas the other options have either incorrect order, reversed electron flow, or incorrect components.
