Eukaryotic Plasma Membrane + Endocytosis

Question 1

What two things does the Eukaryotic Plasma Membrane contain?

Answer 1

Carbohydrates and Sterols

Question 2

What three functions do Carbohydrates have in the Eukaryotic Plasma Membrane?

Answer 2

1. Cell to cell Signaling and Binding
2. Receptor sites
3. Bacterial and Viral Adhesion sites

Question 3

Sterols are Complex Lipids in the Eukaryotic Plasma Membrane…. What is their function?

Answer 3

To Strengthen the Plasma Membrane against Osmotic Lysis

Question 4

What are the six ways materials can enter a cell?

Answer 4

-Passive Transport (Simple or Facilitated
diffusion)
-Active Transport
- Endocytosis
*Osmosis is also a form of Passive
Transport

Question 5

What are the three types of Eukaryotic Endocytosis

Answer 5

1. Phagocytosis
2. Pinocytosis (cellular drinking)
3. Receptor Mediated Endocytosis (Similar to Pinocytosis)

Question 6

A cell sending out Projections of it’s Membrane (Pseudopods), that Surround it’s Target, and then Incorporate it into the cell
is known as….

Answer 6

Phagocytosis

Question 7

The cell membrane folds into the cell creating a divot, causing the rest of the membrane to collapse on top of it is known as….

Answer 7

Pinocytosis (Cellular Drinking)

Question 8

Which type of Eukaryotic Endocytosis is one of the ways a virus can enter a cell and is similar to Pinocytosis?

Answer 8

Receptor Mediated Endocytosis

Question 9

Which type of Eukaryotic Endocytosis occurs once a Ligand binds to the correct Receptor in the Membrane?

Answer 9

Receptor Mediated Endocytosis
