Active Transport and Energy Usage

Which definition is Active Transport?

• One uses energy and goes against the concentration gradient

• One uses energy and goes with the concentration gradient

• One does not use energy and goes against the concentration gradient

• One does not use energy and goes with the concentration gradient

Match the following

• against the concentration gradient

• does not use energy

• Active transport

• Active transport

• Passive transport

• Passive transport

• with the concentration gradient

• Uses energy

Active transport is the movement of particles ​​ (a)   the concentration gradient (​ (b)   to ​ (c)   ). It requires ​ (d)   (energy).​ ​ ​

• low

• high

• ATP

• againts

Answer explanation

Active transport moves particles against the concentration gradient, from low to high concentration, requiring ATP (energy) to do so.

• Sodium Potassium Pump

• 
• Exocytosis

Match the following types of passive transport with the correct diagram.

• Osmosis

• 
• Facilitated Diffusion

• 
• Simple diffusion

• 

Passive transport ​ (a)   require energy to move a molecule from ​ (b)   to ​ (c)   concentration.

• does not
• high
• low
• does
• medium

There are 3 forms of ​ (a)   transport. They do ​ (b)   require the use of ​ (c)   energy. They are: osmosis, diffusion and faciliated diffusion.​ ​

• passive
• not
• ATP

The diagram represents the movement of three different substances across a cell membrane.

• 2 only

• 3 only

• 1 and 2

• 1 and 3
