[Q]: While photosystem II photolyzes water to obtain and energize new electrons, photosystem I simply reenergizes depleted electrons at the end of an electron transport chain. Normally, the reenergized electrons are taken by NADP+, though sometimes they can flow back down more H+-pumping electron transport chains to transport more hydrogen ions into the thylakoid space to generate more ATP. This is termed cyclic photophosphorylation because the electrons are recycled. Cyclic photophosphorylation is common in C4 plants, which need more ATP than NADPH.
[A]: What usually takes reenergized electrons?

[Q]: As the terrain is generally arid, the hills have mostly poor soil and support only cacti and succulent plants. During the rainy season the area turns green with vegetation and grass. The eastern part of the island is greener as it receives more rainfall. A 1994 survey has revealed several hundred indigenous species of plants including the naturalized varieties of flora; some growing in irrigated areas while the dry areas are dominated by the cacti variety. Sea grapes and palm trees are a common sight with mangroves and shrubs surviving in the saline coastal swamps. Coconut palm was brought to the island from the Pacific islands. Important plants noted on the island are:

[Q]: The League of American Bicyclists gave Tucson a gold rating for bicycle friendliness in late April 2007. Tucson hosts the largest perimeter cycling event in the United States. The ride called "El Tour de Tucson" happens in November on the Saturday before Thanksgiving. El Tour de Tucson produced and promoted by Perimeter Bicycling has as many as 10,000 participants from all over the world, annually. Tucson is one of only nine cities in the U.S. to receive a gold rating or higher for cycling friendliness from the League of American Bicyclists. The city is known for its winter cycling opportunities. Both road and mountain biking are popular in and around Tucson with trail areas including Starr Pass and Fantasy Island.
[A]:
Who said Tucson is bicycle-friendly, in 2007?
