Question
Gated ion channels
4) require ATP hydrolysis.
_____________________
The sodium-potassium pump in the plasma membrane of cells
4) carries out a direct exchange of Na+ and K+.
_____________________
In exocytosis, dissolved materials move from fluid
1)are found only on vesicles. 2)move molecules against an electrochemical gradient. 3) open and close in response to a stimulus.4) require ATP hydrolysis.
_____________________
The sodium-potassium pump in the plasma membrane of cells
1) uses chemical energy to generate chemical gradients. 2) converts ADP and Pi to ATP. 3) transports Na+ and K+ out of the cell.4) carries out a direct exchange of Na+ and K+.
_____________________
In exocytosis, dissolved materials move from fluid
in the Golgi apparatus to fluid in the endoplasmic reticulum. in vesicles to fluid outside of cells. in lysosomes to the cytosol. in the cytoplasm to fluid in the nucleus.Explanation / Answer
Gated ion channels open and close in response to a stimulus (e.g., change in voltage across the membrane , mechanical stress or binding of a ligand )
The sodium-potassium pump in the plasma membrane uses chemical energy to generate chemical gradients.(from ATP)
In exocytosis dissolved materials move from fluid in vesicles to fluid outside of cells.(vesicles from ER fuses with plasma membrane and pour its contents outside the cell).
