Ch. 5 Diffusion, Osmosis, Enzymes

Types of Transport

Name/ Describe 2 substances able to pass directly through the plasma membrane

Name/ Describe 2 substances that need a channel protein in order to move inside the cell

Describe the difference between passive and active transport using a channel protein

Osmosis

Explain how plant and animal cells handle different types of solutions: hypertonic, isotonic, hypotonic.

How do plant cells differ from animal cells when dealing with water concentrations?

	Diffusion	Osmosis	Active Transport	Exocytosis	Facilitated Diffusion
Is energy required?
Description

Enzymes:

Explain activation energy in association to enzymes and describe the difference between a reactant and a product.

How do enzymes bind a substrate molecule? Why do we have so many enzymes in our body?

What are the types of enzyme inhibitors and how do they affect the enzyme activity?
