During the charge separation stage of the thylakoid reactions in photosynthesis, what occurs?
A
Electrons are transferred from water to NADP+
B
Electrons are excited and transferred from chlorophyll to an electron acceptor
C
Carbon dioxide is fixed into organic molecules
D
ATP is synthesized from ADP and inorganic phosphate
Verified step by step guidance1
Understand the context: The thylakoid reactions are part of the light-dependent reactions in photosynthesis, occurring in the chloroplasts.
Identify the key components involved: Chlorophyll, electron acceptors, water, NADP+, carbon dioxide, ADP, and inorganic phosphate.
Focus on the role of chlorophyll: Chlorophyll absorbs light energy, which excites electrons within the chlorophyll molecule.
Explain electron transfer: The excited electrons are transferred from chlorophyll to an electron acceptor, initiating the electron transport chain.
Clarify the outcome: This electron transfer is crucial for the synthesis of ATP and NADPH, which are used in the Calvin cycle to fix carbon dioxide into organic molecules.
