Based on the data, identify the shrubs and data point where the greatest flow of electrons through chloroplast electron transport chains most likely occurs.

Thylakoid membrane and Krebs cycle.

Explanation:

Thylakoid membrane is the region in the chloroplast where electron transport chains occur while the Krebs cycle is the stage in which this electron transport chains occurs and produces large number of ATP. If the electron transport chain does not occur, very low amount of ATP is produce because electron transport chain is responsible for the production of high amount of ATP.
