There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. This process is in contrast to passive transport , which allows molecules or ions to move down their concentration gradient, from an area of high concentration to an area ...
Secondary active transport is when one solute moves down the electrochemical gradient to produce enough energy to force the transport of another solute from low concentration to high concentration. [ citation needed ] An example of where this occurs is in the movement of glucose within the proximal convoluted tubule (PCT).

Unlike the first revival, which wholly concerned itself with traditional music, the second revival was a part of the birth of non-traditional contemporary folk music. Like the American revival, it was often overtly left wing in its politics, and the leading figures, the Salford-born Ewan MacColl and A. L. Lloyd , were both involved in trade ...
Wales is a Celtic country that features folk music played at twmpathau (communal dances) and gwyl werin (music festivals). Welsh music also includes male voice choirs and songs accompanied by a harp. Having long been subordinate to English culture, Welsh musicians in the late 20th century had to reconstruct traditional music when a roots ...
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
