question 4

Multiple Choice

-The light reactions are generally presented in zig-zag patterns, as shown in the accompanying figure which has an implied amount of energy on the vertical axis. 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.
