Question

question: after photons strike the light-absorbing pigment chlorophyll, which of the following occurs first? answer options: select one of four electrons in water get released during photolysis. electrons are transported through etc. atp is transformed into glucose. electrons in chlorophyll become excited.

Explanation:

When photons strike chlorophyll, the first event is the excitation of electrons within chlorophyll. Photolysis (release of electrons from water) happens later to replace the excited electrons. Electron transport chain (ETC) and ATP to glucose transformation are subsequent steps in photosynthesis. So the first event is electrons in chlorophyll becoming excited.

Answer:

Electrons in chlorophyll become excited.
