The iPhone 8 and iPhone 8 Plus are smartphones developed and marketed by Apple Inc. They are the eleventh generation of the iPhone . The iPhone 8 was released on September 22, 2017, succeeding the iPhone 7 and iPhone 7 Plus , respectively.
Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .
This plastoquinol is later oxidized back to PQ, releasing the 2e-to the cytochrome b 6 f complex and the two H + ions into the thylakoid lumen. The electrons then pass through Cyt b 6 and Cyt f to plastocyanin , using energy from photosystem I to pump hydrogen ions (H + ) into the thylakoid space.
Similarly, "C" was used to denote the lower-priced iPhone 5C, a variant of the iPhone 5 with similar features and internals, and is the only iPhone with "C" in its name. iPhone X (pronounced "10"), iPhone XR (pronounced "10R") and iPhone XS and XS Max (pronounced "10S") are currently the only iPhones to have been branded with Roman numerals (X).
The iPhone, developed by Apple Inc., is a line of smartphones that combine a mobile phone, digital camera, personal computer, and music player into one device. Introduced by then-CEO Steve Jobs on January 9, 2007, the iPhone revolutionized the mobile phone industry with its multi-touch interface and lack of physical keyboard.
Up to the iPhone 8 and 8 Plus, iPhones had a single button on the front panel, with the iPhone 5s and later integrating a Touch ID fingerprint sensor. Since the iPhone X , [ note 2 ] iPhone models have switched to a nearly bezel -less front screen design with Face ID facial recognition in place of Touch ID for authentication, and increased use ...
Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants , algae , and cyanobacteria .
Oxygenic photosynthesis can be performed by plants and cyanobacteria; cyanobacteria are believed to be the progenitors of the photosystem-containing chloroplasts of eukaryotes. Photosynthetic bacteria that cannot produce oxygen have only one photosystem, which is similar to either PSI or PSII .
