Active Transport - Secondary Active Transport

Secondary Active Transport

In secondary active transport or co-transport, energy is used to transport molecules across a membrane; however, in contrast to primary active transport, there is no direct coupling of ATP; instead, the electrochemical potential difference created by pumping ions out of the cell is used.

The two main forms of this are antiport and symport.

Famous quotes containing the words transport, secondary and/or active:

    One may disavow and disclaim vices that surprise us, and whereto our passions transport us; but those which by long habits are rooted in a strong and ... powerful will are not subject to contradiction. Repentance is but a denying of our will, and an opposition of our fantasies.
    Michel de Montaigne (1533–1592)

    Cloud-clown, blue painter, sun as horn,
    Hill-scholar, man that never is,
    The bad-bespoken lacker,

    And stones, only this imager.
