The concentration of glucose is higher inside an animal cell than outside. however, the cell needs a lot of glucose. what kind of transport system does the cell use (active or passive) to transport more glucose into the cell?

Active transport

Explanation:

This is movement of molecules and ions against their concentration gradients with the use of ENERGY  as ATPs.

In this case, glucose molecules  moved against  their  larger number inside the cells,.Therefore extra energy is needed to push these molecules to reach the target  sites in cells, from outside against the crowded molecules already present inside the cells. Unlike passive transport where molecules move down there gradient. for example water moving into a dry soil in the desert.
