The process that moves sodium ions from an area of relatively low concentration inside a cell to an area of higher concentration outside the cell is called
A) osmosis.
B) facilitated diffusion.
C) active transport.
D) exocytosis.
E) diffusion.

Question

Quizplus · Accepted Answer

The process described in the question involves moving ions against their concentration gradient (from low to high concentration), which requires the input of energy. This process is known as active transport. Options A, B, D, and E do not involve the movement of ions against their concentration gradient, and therefore do not require energy input.
