Active transport is a cellular process which moves molecules against their concentration gradient, using specialized proteins and energy from atp or from another. WebActive transport is the movement of molecules against their concentration gradient, using specialised carrier proteins and energy in the form of adenosine triphosphate (). This ATP is generated from cellular metabolism and is needed to change the conformational shape of the carrier proteins.. This type of transport is different from the passive forms of …
WebSam. An "electrochemical gradient" is a combination of two factors: an "electrical potential difference" between the inside and outside of the membrane and a "concentration gradient." In Khan's example, the "electrochemical graident" is established due to the sodium/potassium pump and the carrier protein's ability to allow potassium to travel ... WebActive Transport. Active transport is the term reserved for transport processes that result in the movement of a solute uphill or against its natural direction. For the case of a neutral solute (at constant temperature and pressure), this resolves into movement against a concentration difference; for a charged solute, it is movement against the ...
