Morphology

photochemical + exchange

The phrase is directly compositional: 'photochemical' denotes chemical action driven by light and 'exchange' denotes a swapping or transfer, so the combined meaning 'an exchange caused by light-driven chemical action' follows straightforwardly from the parts. This follows regular English compounding and the 'photo-' prefix is cross-linguistically recognizable, so a learner who knows the constituent words would readily infer the MWE meaning.

Etymology

Photochemical exchange uses the part photo, meaning 'light', and exchange, meaning a 'swap'. Imagine sunlight hitting molecules and making them change partners so atoms or groups move from one molecule to another. So, the phrase means 'an exchange resulting from the chemical action of light'.
