Chlorophyll a
What happens to the oxygen atom produced through the process of photolysis?
It combines with another oxygen atom to form an oxygen molecule (O2)
What captures the excited electrons and transfers them to the primary electron acceptor during photosynthesis?
Photosystem I
What is the ultimate source of energy for driving the synthesis of ATP and NADPH during photosynthesis?
Light energy
What organelle allows plants to harvest energy from sunlight to carry on photosynthesis?
Chloroplast
Which pigment in the chloroplast absorbs sunlight for photosynthesis?
Chlorophyll
What does ATP stand for and what is its role in photosynthesis?
Adenosine triphosphate; release energy when phosphate bonds are hydrolyzed
Which protein accepts a pair of electrons from the cytochrome complex in the electron transport chain?
Plastocyanin
What is the role of NADPH in the process of photosynthesis?
Temporarily store energized electrons produced during the light reactions
