FC cell membrane and transport

The cell membrane is also known as:

• the plasma membrane

• phospholipid bilayer

• fluid mosaic

• all of the above

Transport of small uncharged molecules through the cell membrane that does not require energy

• active transport

• passive transport

• endocytosis

• exocytosis

passive transport moves from a ___ concentration. to a ____ concentration

• high, high

• low, low

• low, high

• high, low

The diffusion of water is called:

• passive transport

• aquiporin

• osmosis

• exocytosis

A solution with a higher amount of solute

• hypotonic

• hypertonic

• isotonic

The movement of large particles through the cell membrane or against the concentration gradient requires energy and is called:

• active transport

• passive transport

• osmosis

• diffusion

The concentration of solute inside and outside of the cell is equal

• isotonic

• hypotonic

• hypertonic

The heads of the phospholipids in the cell membrane are "water loving" or

• hydrophillic

• hydrophobic

• osmosis

• isotonic

The tails of the phospholipids in the cell membrane are "water fearing" or

• hydrophillic

• hydrophobic

• osmosis

• isotonic

Passive movement of molecules along their concentration gradient through the cell membrane with the help of a channel protein

• exocytosis

• active transport

• facilitated diffusion

• simple diffusion
