Cell Transport/Homeostasis

Diffusion is a form of __________ transport.

• Passive

• Active

• Easy

• Free

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

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

The general name for movement of substances across cell membranes without need of energy input

• passive transport

• active transport

After diffusion has occured & the concentrations are the same on both sides of a membrane, the substance is said to be in _________ ____________ .

• exocytosis

• dynamic equilibrium

• net movement

• facilitated

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water
