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 occurred & 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 (a)   across a membrane.

Some cells move large particles OUT of the cell through the process of:

• Protein Synthesis

• Endocytosis

• Exocytosis

• Cytoplasmic Streaming
