In ________, One Substance is Transported into the Cell and Another

Question

In ________, one substance is transported into the cell and another is transported out.
A) cotransport
B) ditransport
C) countertransport
D) protransport
E) throughtransport

Accepted Answer

Countertransport, also known as antiport or exchange transport, involves the simultaneous but opposite movement of two substances across a membrane. One substance is moved into the cell while the second substance is moved out. This type of transport is essential for the maintenance of concentration gradients and the overall homeostasis of the cell.
