I know it's a lot but it would really help...here it goes!! 2.
List the main components of the cell membrane.


3.
Why is the cell membrane referred to as the lipid bi-layer?


4.
Explain the functions of the proteins found in the cell membrane.


5.
How is the cell membrane similar to your skin?


6.
Why is the cell membrane referred to as semi-permeable? How does it maintain
homeostasis


7.
How are carbohydrates used in cell recognition?


8. How is the cell membrane involved in cell-cell communication?



9.
Why is the plasma membrane always represented by the fluid mosaic model?

2.)The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

3.)The lipid bilayer is a universal component of all cell membranes. Its role is critical because its structural components provide the barrier that marks the boundaries of a cell. The structure is called a "lipid bilayer" because it is composed of two layers of fat cells organized in two sheets.

4.)For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location (Figure 4).

5.)The cell membrane is like the skin of a human because it protects the outside layer, so does the cell membrane. The nuclear envelope is like the skull of a human because it protects the brain, just like the nuclear envelope protects the nucleus.

6.)One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, non-polar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

7.)Abstract. Complex carbohydrates coat the surfaces of cells and have the potential to carry the information necessary for cell-cell recognition. Sugar-specific receptors (lectins) are also present on cells and can interact with sugars on apposing cells.

8.)Your cell membrane plays an integral role in cellular communication because it holds the proteins, carbohydrates, and other molecules that are essential to cellular communication. These communications may come from signaling molecules sent by other cells, from cell-to-cell interactions, or from within the cell itself.

in addition to spreading humanist ideas, erasmus has contributed to criticism of corruption in the church.

maybe because its impossible for balloons to lift a whole entire house.
