Secondary active transport moves substances against their concentration gradient

Question

Secondary active transport moves substances against their concentration gradient by:

A. Cleaving ATP with an ATPase enzyme to pump the molecule across the membrane.

B. Moving substances along with Na+ as Na+ is carried down the Na+ concentration gradient.

C. Moving substances in the opposite direction of Na+ as Na+ is carried down the Na+ concentration gradient.

A, B, and C.

just B and C

just B and C

Explanation / Answer

ans is..A.B.C

secondary active trasnport ATP is used which is genrated with the down the concentration gradient of some other molecule whose movement is coupled with another molcule.

like here Na is transported down hill which generated ATP now yhis ATP is used to transport a molecule against the concentration gradient whose movement is coupled and is opposite to that of Na
