The electrons donated by chlorophyll molecules during noncyclic photophosphorylation do not come back to the chlorophyll molecules.

Explanation

(1) he electrons donated by chlorophyll molecules during the process of noncyclic photophosphorylation are retained by NADP (Nicotinamide adenine dinucleotide phosphate) and the flow of electrons is continued due to `OH^(-)` ions formed during the photolysis of water.
(2) The electrons donated by chlorophyll molecules during noncyclic photophosphorylation, therefore, do not come back to chlorophyll molecules.
