Differentiate between active and passive transport. What are the differences between them?
Active transport requires energy while passive transport doesn't require energy. Active transport is low to high, passive transport is high to low.
Active transport doesn't require energy while passive transport requires energy. Passive transport is low to high, active transport is high to low.
Develop an analogy for the plasma membrane. We talked about many examples in class. (Plasma membrane is like a ____.) Explain how that analogy relates to the function of the plasma membrane. Why did you pick this one?
What is the difference between endocytosis and exocytosis? What type of transport are they?
Endocytosis brings molecules in while exocytosis pushes molecules out.
Exocytosis brings molecules in while endcytosis pushes molecules out.
What is facilitated diffusion? What type of transport is it?
Facilitated diffusion is diffusion that has transport protein. It is a passive protein.
Facilitated diffusion is diffusion that has receptor protein. It is an active protein.
What type of protein acts as a tunnel or channel to bring substances in and out of the cell?
Transport protein
Receptor protein
Active transport - substanceas move from ___ to ___ concentrations.
high, low
low, high
Passive transport - substances move from ___ to ___ concentrations
high, low
low, high
In the plasma membrane, which molecule prevents the tails of the phospholipids from sticking together?
Osmosis
Cholesterol
Carbohydrates
Diffusion
What is the function of the plasma membrane? What does it help maintain?
It stops the plasma membrane from sticking from each other
It allows substances to go through
It provides protection for a cell. It helps maintain a homeostasis
