• enzymatic reactions

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

• passive transport

• active transport

Osmosis is the movement of _____ across a membrane.

• Endocytosis

• Exocytosis

• Cytoplasmic Streaming

• Diffusion 
• Endocytosis
• Exocytosis 

The sodium potassium pump is an example of

• Passive Transport

• Active Transport

• Facilitated Diffusion

• Endocytosis

Human red blood cells contain 0.9% sodium chloride as a component of their cytoplasm. What would happen if an IV solution containing 3.5% sodium chloride is introduced into a person? 

• The red blood cell would get bigger and burst.

• The red blood cell would stay the same size.

• The red blood cell would shrink.

• The red blood cell would first loose water and then absorb water.
