Passive Transport uses ____ energy

• no

• a lot of

• a little bit of

• some

_____________ is the free movement of particles across the membrane with the concentration gradient

• diffusion

• facilitated diffusion

• active transport

• fusion

An example of diffusion is

• CO₂ and O₂ exchange in the lungs

• Glucose transport

• Na⁺ / K⁺ Pumps

• Exocytosis

What is the movement of particles with the concentration gradient using protein "helpers"?

• diffusion

• facilitated diffusion

• active transport

• enzymatic reactions

An example of facilitated diffusion is

• CO₂ and O₂ exchange in the lungs

• Glucose transport

• Na⁺ / K⁺ Pumps

• Endocytosis

What is a difference between diffusion and facilitated diffusion?

• movement of particles from high to low

• One uses a protein "helper" and the other doesn't

• movement of particles from low to high

• One uses energy and the other doesn't
