(9) What does selectively permeable mean? Why is the cells ability to do so important?

(10) Describe how the following are important in the makeup of the cell membrane:
1. Phospholipid bilayer
2. Proteins
3. Carbohydrates
4. Cholesterol

Respuesta :

Answer:

1. prokaryotic and Eukaryotic

2. cellular organism that lacks an envelope-enclosed nucleus.

3. organisms whose cells have a nucleus enclosed within a nuclear envelope.

4. both have a cell membrane

5. a plasma membrane: an outer covering that separates the cell's interior from its surrounding environment.

cytoplasm: a jelly-like cytosol within the cell in which other cellular components are found.

DNA: the genetic material of the cell.

ribosomes: where protein synthesis occurs

6. Bacteria, E. coli

7. Animals, plants

8. plasma membrane

9. Selective permeability of the cell membrane refers to its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.  Allowing some molecules through while blocking others.

10. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. 

Specialized proteins in the cell membrane regulate the concentration of specific molecules inside the cell.

Membrane carbohydrates perform two main functions: participate in cell recognition and adhesion, either cell-cell signaling or cell-pathogen interactions, and they have a structural role as a physical barrier. 

Cholesterol plays has a role in membrane fluidity but it's most important function is in reducing the permeability of the cell membrane.
