How many bones are in the adult skeleton?
3.

What functional group anchors cholesterol to the phospholipid bilayer?
4.

Carbohydrates that are associated with proteins are called____.
5.

Carbohydrates associated with lipids are called
6.

See a "sugar coating of the cell" called the
7.

Functions of the cell membrane:
- A.
  
  Transport
- B.
  
  Barrier
- C.
  
  Enzymatic Capabilities
- D.
  
  Receives Signals
- E.
  
  Structure
- F.
  
  Recognition
- G.
  
  Connectivity
- H.
  
  Thermoregulation
8.

____ act like cell identity markers. (more specific than receptors)
9.

3 Types of cell junctions: (plural forms) ____ ____, ____ ____, and _____.
10.

"zipper like connection between cells" that wrap around the cell firmly connected together
- A.
  
  Gap junctions
- B.
  
  Tight junctions
- C.
  
  Desmosomes
11.

Proteins that make up tight junctions
12.

The ___-____ _____ is the passageway for things to move in between cells from one surface of tissue to the next. Tight junctions literally seal off this passageway and prevent leakage: they form an impermeable seal that prevents certain substances from crossing.
13.

They "adhere" cells together--especially in tissues that experience a lot of stretching/ are subject to mechanical distortion (i.e. in heart cells, in uterus when infant develops within)
- A.
  
  Tight junctions
- B.
  
  Desmosomes
- C.
  
  Gap junctions
14.

Tight junctions compartmentalize the cell membrane producing different sides of the cell membrane: the ____ surface and ____ surface.
15.

Prevent us from swelling up in the shower:
- A.
  
  Desmosomes
- B.
  
  Tight junctions
- C.
  
  Gap junctions
16.

This part of membrane faces the body or lumen surface
17.

Desmosome's linker proteins that make up the intracellular filaments that extend from protein plaques across the para-cellular pathway are called:
18.

The cytoplasm of cells are connected to their neighboring cells, and particles can be exchanged. This allowance for direct communication is found in body areas where cells must communicate to each other through direct physical connection (i.e. heart cells because heart is a 4 chambered organ that needs to communicate and contract in unison, osteocytes (bone cells) need to contact cells on the surface to gain nutrients for survival.)
- A.
  
  Desmosomes
- B.
  
  Tight junctions
- C.
  
  Gap junctions
19.

They also compartmentalize the cell membrane producing different sides of the cell membrane.
- A.
  
  Tight junctions
- B.
  
  Desmosomes
- C.
  
  Gap junctions
20.

"pipe-like" connection between cells; "communicating junctions"
- A.
  
  Tight junctions
- B.
  
  Gap junctions
- C.
  
  Desmosomes
21.

Grouping of proteins that interact with each other and form a single structure on the intracellular side of the cell membrane (in desmosome)
22.

This surface faces the other side
23.

"button-like connection"
- A.
  
  Tight junction
- B.
  
  Desmosome
- C.
  
  Gap junction
24.

If the luminal surface is towards the body surface (not lumen), then it's called the ___ surface.
25.

Individual proteins that make up gap junctions are called
