Cellular Transportation - Vocabulary Review

The two-layer "sandwich" of molecules that surrounds a cell

• phospholipids

• marker proteins

• cell wall

• phospholipid bilayer

Passive cell transport that moves particles from an area of high concentration to low concentration

• simple diffusion

• active transport

• facilitated diffusion

• receptor mediated transport

Membrane characteristic that allows the entry of some substances but blocks the entry of others.

• proteins

• fluidity

• selectively permeable

• phospholipid bilayer

The passive transport of water across a membrane.

• facilitated diffusion

• simple diffusion

• osmosis

• active transport

Passive cell transport that uses proteins to aid in the transport of certain materials across a membrane.

• simple diffusion

• osmosis

• active transport

• facilitated diffusion

Movement of molecules across a membrane from an area of low concentration to high concentration. Requires energy (ATP used) to happen.

• osmosis

• active transport

• passive transport

• facilitated diffusion

The movement of molecules across the cell membrane is balanced, equal concentration is reached on both sides of the membrane.

• exocytosis

• equillibrium

• concentration gradient

• osmosis

Process of exporting materials from a cell by a vesicle fusing with the cell membrane (materials exit the cell).

• exocytosis

• endocytosis

• equillibrium

• diffusion

Process by which a cell takes material into the cell by infolding of the cell membrane

• exocytosis

• endocytosis

• diffusion

• passive transport
