The Light Reactions Are Generally Presented in Zig-Zag Patterns,as Shown

Multiple Choice

The light reactions are generally presented in zig-zag patterns,as shown in the accompanying figure.What is the significance of the primary electron receptor shown at position 2 being slightly higher than the primary electron receptor shown at position 3?

A) The electron that has been accepted gains energy as it leaves the primary electron receptor at 2 and heads to the primary electron receptor at position 3.
B) The primary electron receptor at 2 has slightly less energy than the primary electron receptor at position 3.
C) The primary electron receptor at position 2 comes before the primary electron receptor at position 3.
D) Since electrons have given off energy in the electron transport chain,they can be boosted higher by the second photosystem. Answer B
