Transport across the membrane

Transport of molecules across the cell membrane that requires energy.

• active transport

• passive transport

Some molecules need the help of membrane proteins to move molecules from areas of high concentration to areas of low concentration.

• active transport

• facilitated diffusion

• diffusion

• osmosis

• cytoskeleton filaments

• phospholipids

• channel proteins

• cholesterol plaques

Energy for active transport comes from the cells

• Golgi complex

• mitochondria

• nucleus

• lysosome
