Cotransport always involves Na+ and a non -ionized solute (such as glucose)

/in /by

Which of these statements are correct and which are incorrect? 1- Cotransport always involves Na+ and a non -ionized solute (such as glucose).

2- Cotransporters can move their transported solutes in either direction across a cell membrane.

3- Cotransport consumes metabolic energy directly.

4- Counter-transport always requires Na+ participation.

5- Facilitated diffusion and primary and secondary active transport are all examples of carrier -mediated transport.

6- The energy for secondary active transport comes indirectly from the activity of the Na+, K+ ATPase.

 

 

48- Place each of these into its appropriate category.

Facilitated diffusion, Primary active transport , Secondary active transport

1- Coupled transport of glucose and Na+ into cells.

2- Coupled transport of Na+ into cells and K+ out of cells.

3- Movement of glucose from the interstitial fluid into cells.
