Feedback: Feedback: Learning Objective: Describe how electrons move through the electron transport chain and whathappens to their energy levelsQuestion 10 of 40To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a “chlorophyllmeter” that measures the amount of green light reflected off a leaf.Why does this provide an indication of whether the plant may need more or less nitrogen?A. Nitrogen gas is green, and photosynthesis uses N2 to run the Calvin cycle.B. Each chlorophyll molecule contains four nitrogen atoms that surround the Mg2+ ion, and these account formost of the nitrogen in a leaf.C. Nitrogen ions form the electrochemical gradient across the thylakoid membrane that drives ATP synthesis.D. Beta-carotene is composed largely of nitrogen atoms, and has a similar absorption to chlorophyll.
