Question

There are 30 sodium ions found outside the cell and 10 inside the cell. If the cell is utilizing active transport to move these molecules, where will the sodium ions travel?

Answer 1

Outside the cell (high concentration)

Step-by-step explanation:

Active transport is one of the two types of transports in which energy (ATP) is used to move particles across a membrane. In other words, active transport involves moving a substance from lower concentration to a higher concentration.

In this question, there are said to be 30 sodium ions found outside the cell and 10 inside the cell. If the cell is utilizing active transport to move these molecules, the sodium ions will travel outside the cell from inside of the cell. That is, from inside the cell (10) to outside the cell (30).
