Why is the photosynthetic electron transport chain sometimes referred to as the "Z scheme"?
A)Because the energy level of the electrons increases and decreases and increases and decreases.
B)Because the electrons zigzag through the antenna chlorophyll molecule to get to the reaction center.
C)Because the electrons zigzag through the electron transport chain as they travel from one photosystem to another in the thylakoid membrane.
