• Nothing can move through the membrane

• All molecules can pass through the membrane.

What is equilibrium?

• When concentrations cannot be balanced between two substances 
• When concentrations are balanced between two substances

In a "high concentration," molecules

• are spread out

• are tightly packed together

• are uncrowded

• are unevenly dispersed

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

Movement of molecules through the cell membrane from high to low concentration

• passive transport

• active transport

Active transport moves substances against a concentration gradient 

• true
• false 

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis

Which is NOT a form of active transport?

• Endocytosis
• Osmosis
• Exocytosis
• Pinocytosis

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 

When cells form a vesicle to release materials, which form of transport is occurring? 

• Endocytosis
• Exocytosis
• Facilitated Diffusion
• Osmosis
