What is the process called in which electron transport chain components move along an electrochemical gradient to produce ATP in the presence of light?

Explanation

Photophosphorylation is the process where electrons are transferred through a series of carriers along an electrochemical gradient during photosynthesis, resulting in the formation of ATP in the presence of light. Photoperiodism relates to the effect of day length on organisms, while photosynthesis encompasses the overall process of converting light energy into chemical energy.
