a.
To determine:
In which direction( into the cell or out of the cell) would the Na+ be transported if the transport protein in the cell membrane was: an ATPase pump.
Concept introduction:
ATPase pump: it is an enzyme found in the plasma membrane of animals cells. It performs many functions in the cell physiology like it pumps solutes.
b.
To determine:
In which direction( into the cell or out of the cell) would the Na+ be transported if the transport protein in the cell membrane was an ion transport operating under facilitated transport.
Concept introduction:
Facilitated diffusion: It involves the passive movement of molecules by facilitated transport along their concentration gradient by the presence of another molecules, generally an integral memebrane protein forming a pore or channel.
