Cell Transport - Benchmark

Cellular Transport

Multiple Choice

What similarity do these two modes of water transport share?

• Both require free energy.

• Both utilize transport proteins.

•  Both are spontaneous processes.

• Both change the structure of the cell membrane.

Multiple Choice

Which of the following statements best describes the lipid bilayer of a cell membrane?

• Nonpolar molecules are positioned towards the outer edges o f the bilayer.

• The lipid bilayer is composed mostly of polysaccharides and proteins.

• The polar heads are positioned to interact with the inside and outside of a cell.

• The bilayer has two rigid sections that prevent molecules from entering a cell.

Multiple Choice

What similarity do active transport and passive transport systems share?

• Both require energy from ATP in order to transport particles.

• Both lead particles from an area of high concentration to low concentration.

• Both move particles across the cell membrane.

• Both specialize in transporting water in and out of cell organelles.

Multiple Choice

Active transport is movement of particles through the cell membrane from a region of ...1... to a region of ...2... using energy in the form of ...3...

• 1: lower concentration, 2: higher concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: ATP

• 1: lower concentration, 2: higher concentration, 3: ATP

Multiple Choice

Even though the concentration of salt is high in some gland cells and low in the blood, these cells can move salt out of blood and into the cells.  This is an example of

• passive transport

• active transport

• diffusion

• osmosis

Multiple Choice

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases 

• Active uses hormones and passive does not 

Multiple Choice

Passive transport moves materials in what direction?

• low to high

• left to right

• east to west

• high to low

Multiple Choice
