Answer:
The best answer to the question: The primary function of light absorption by photosystems I and II is to produce: ____, would be: Free, energized electrons.
Step-by-step explanation:
In order for plants to be able to carry out their photosynthetic processes, with which they are able to activate the different molecules that will provide them with necessary energy, the light of the sun is necessary. Through two different photosynthetic systems known as photsystem I (PSI) and photosystem II (PSII), plants can absorb radiation of different wavelengths thanks to the pigments present in these systems. These pigments activate at the contact with shortwave, and wavelength and capture them and the systems also possess a special pair of clorophyll molecules at the reactive center that will activate. The whole process will, in the end, produce free, energized electrons.
