ACTIVE TRANSPORT 12919

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 

What are 3 types of active transport?

• Riding a bike, Running through the mountains, walking on the beach
• Osmosis, Diffusion, Facilitated Diffusion
• Sodium/potassium Pump, Endocytosis, Exocytosis
• Throwing a ball, Playing tennis, driving a car

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Which form of active transport is being shown?

• Facilitated Diffusion
• Exocytosis
• Endocytosis
• Protein Pumps

Active transport moves molecules from a low concentration to a high concentration

• True
• False

The difference in the concentration of a substance from one location to another is called 

• diffusion
• osmosis
• concentration gradient
• passive transport

A common biological cycle is shown below. ATP is used to

• transport molecules in cell by active transport

• transport water across a membrane by diffusion

• transport molecules from a high to a low concentration

• balance nutrients in root cells

The diagram above shows the results of the net movement of a specific kind of molecule across a living cell membrane.The movement of molecules from side A to side B is an example of the process of

• diffusion

• cellular respiration

• chromatography

• active transport

The diagram above shows two cells viewed using the same magnification with the same microscope. One possible claim that can be made about the activity of these two cells is that

• more active transport occurs in cell B than in cell A

• more active transport occurs in cell A than in cell B

• cell B uses some of the extra mitochondria to make food

• cell A is a plant cell since it has a cell wall
