How do sugar molecules cross the cell membrane?

The correct answer is - through facilitated diffusion and active transport.

Explanation:

Glucose is a six-carbon sugar molecule that is directly utilized by cells to provide energy. A glucose molecule is large enough to go through a cell membrane with simple diffusion.  

Cells help glucose molecules to cross the cell membrane through facilitated diffusion and active transport. Active transport is of two types primary and secondary active transport to help the glucose molecule to cross the membrane.

Thus, the correct answer is - through facilitated diffusion and active transport.
