Biology TEKS 5.C - Passive Transport

This cellular process occurs in the plasma membrane, and it is critical for homeostasis, as it controls the movement of molecules in and out of the cell.

This example of Passive Transport allows small molecules like oxygen and carbon dioxide to pass through the cell membrane. Molecules move from High to Low Concentration.

Tags

TX.112.42.C.5.C.

This example of Passive Transport uses Channel Proteins or Carrier Proteins to move molecules from High Concentration to Low Concentration. Glucose moves into the cell by this form of transport.

TX.112.42.C.5.C.

This example of Passive Transport moves water through the cell membrane (semi-permeable) from an area of High concentration to an area of Low concentration.
