Question
What would happen to a plant that is treated with a chemical that prevents electrons from moving through the electron transport chain?Multiple ChoiceWater would be broken down to form oxygen at a higher rate to compensate.More electrons would be available for the light harvesting array.It could not produce NADP+NADP+ .It could not generate an electrochemical H+H+ gradient across a membrane.It could no longer produce CO2CO2 .
Solution
The plant would not be able to generate an electrochemical H+ gradient across a membrane.
Here's why: The electron transport chain is crucial for the process of photosynthesis in plants. It helps in the creation of a proton gradient, which is used to produce ATP, the energy currency of the cell. If a chemical prevents electrons from moving through the electron transport chain, the plant would not be able to generate this gradient. Without the gradient, ATP cannot be produced efficiently, which would severely affect the plant's energy production and overall growth.

How would the electron transport chain be affected if oxygen was not present in the cell?Multiple ChoiceThe electron transport chain would stop because the carrier proteins would have no way to unload electrons.The electron transport chain would stop until the cell found another source of hydrogen ions.The electron transport chain would continue, but it would produce fewer ATP per glucose molecule.The electron transport chain would continue only if glycolysis continued producing NADH.
