Question

which event occurs in photosystem i?
water molecules are broken apart.
light energy excites electrons.
oxygen is released as waste.
electrons are transferred to ferredoxin.

Explanation:

• In photosystem I, light energy is absorbed by pigments. This energy excites electrons in the reaction - center chlorophyll.
• The excited electrons are then transferred to ferredoxin, a protein.
• Water molecules are broken apart and oxygen is released as waste in photosystem II.

Answer:

Electrons are transferred to ferredoxin.
