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 ...
Active mobility, soft mobility, active travel, active transport or active transportation is the transport of people or goods, through non-motorized means, based around human physical activity. [1] The best-known forms of active mobility are walking and cycling , though other modes include running , rowing , skateboarding , kick scooters and ...
English: Comparison of membrane transport methods. There is passive transport, which includes simple and facilitated diffusion, and active transport. The diagram doesn't show endocytosis or exocytosis (another method of transporting substances across the plasma membrane). The diagram was made on Google Drawings.
Autonomous rail rapid transit (ART) is a lidar (light detection and ranging) guided bi-articulated bus system for urban passenger transport. Developed and manufactured by CRRC through CRRC Zhuzhou Institute Co Ltd , it was unveiled in Zhuzhou in the Hunan province on June 2, 2017.
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).
The Kuching Urban Transportation System (KUTS) is an under-construction Autonomous Rail Rapid Transit (ART) system network that serves Greater Kuching, Samarahan, and Serian. It is the first ART system network to be built outside of China and also the first metro bus system in the state of Sarawak which was touted as one of the methods to ease ...
Openclipart, also called Open Clip Art Library, is an online media repository of free-content vector clip art.The project hosts over 160,000 free graphics and has billed itself as "the largest community of artists making the best free original clipart for you to use for absolutely any reason".
English: In secondary active transport, the required energy is derived from energy stored in the form of concentration differences in a second solute. Typically, the concentration gradient of the second solute was created by primary active transport, and the diffusion of the second solute across the membrane drives secondary active transport.
