It was not until 1953 that James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin figured out the structure of DNA — a double helix — which they realized could carry biological information
The answer is Domain. It is also referred to as Superkingdoms. There are three domains in current classification system namely; Archaea, Bacteria, and Eukarya. The first two classify single-celled organisms whose cells have no nucleus while Eukarya classifies organism that have a nucleus bound by a membrane. The difference between Archaea and Bacteria is their membrane structure; Archaea’s membrane is characterized by membrane lipids that are branched hydrocarbon chains attached to glycerol by ether linkages, while Bacteria’s is made of unbranched fatty acid chains attached to glycerol by ester linkages.
The by-products that cellular respiration include are carbon dioxide and water<span>.</span>
As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce ATP.
In plants and cyanobacteria, a two-step mechanism known as noncyclic photophosphorylation results in the direct production of ATP and NADPH during photosynthesis. High-energy electrons exiting photosystem II are used in the noncyclic photophosphorylation process just outlined to produce ATP, which is then transferred to photosystem I to promote the creation of NADPH.
For every pair of electrons that move from H2O to NADP+ to create a molecule of NADPH, this results in the production of slightly more than one molecule of ATP.
