Question

fill in the blank question

photosynthetic microorganisms produce atp via blank using an electron transport system powered by light.

Explanation:

Identify the mechanism of ATP production powered by light

$$ \text{Light energy} ightarrow \text{Electron Transport System (ETS)} ightarrow \text{Proton Motive Force} ightarrow \text{ATP Synthesis} $$

Match with standard microbiological terminology

$$ \text{ATP production via light-driven ETS} = \text{photophosphorylation} $$

Answer:

Photosynthetic microorganisms produce ATP via <blank>photophosphorylation</blank> using an electron transport system powered by light.
