DCPIP (2,6-dichlorophenol-indophenol), a blue dye, can act as an electron acceptor and becomes colorless when reduced. A suspension of chloroplasts is prepared, and DCPIP is added to the suspension. The sample is split into two test tubes. One test tube is exposed to light and the other is wrapped in foil (dark control). What would you observe over time comparing the light exposed and the dark control test tubes? (1 point) Responses The sample exposed to light stays blue. The sample kept in the dark turns colorless. The sample exposed to light stays blue. The sample kept in the dark turns colorless. The sample exposed to light turns colorless. The sample wrapped in foil stays blue. The sample exposed to light turns colorless. The sample wrapped in foil stays blue. Both samples stay blue. Both samples stay blue. Both samples turn colorless. Both samples turn colorless.
