The membrane separates the ______ and _____ of the cell.
inside and outside (any order)
200
What is the phospholipid tail made out of? Be specific
2 Fatty Acids
200
Wha is the network of fibers called that support the inside of the cell?
Cytoskeleton
200
Because a cell membrane lets certain things through and not others, it is called __________.
Semi-permeable
200
What is the function of a motor protein?
To carry the products that the cell makes (proteins, fats and enzymes)
300
All cells have cell membranes, T or F?
TRUE
300
Which is hydrophobic, head or tail?
tail
300
What is the smallest fiber in the cytoskeleton called and what does it do?
microfilaments, gives the cell its shape (and helps it CHANGE it shape)
300
Name 2 functions of proteins in the cell membrane that are only attached to one side of the membrane.
They can be any 2: 1. ID tags - (act as flags to identify the cell as self) 2. Receive messages (communication) 3. Allow cells to stick to one another 4. Place of attachment for cell's skeleton
300
What is the central hub or railway station for the microtubules and helps to organize all the microtubules when the cell starts to divide?
Centrosome
400
What connects the phosphate group to the fatty acid group?
A glycerol
400
What is the false foot called that helps the cell "ooze" and move?
pseudopod
400
The functional group on a glycerol
OH (alcohol group)
400
What is the centrosome made up of?
2 centrioles
500
The cell membrane is called a _______ bilayer, which means 2 layers.
Phospholipid
500
What can act as channels to help larger molecules or non-polar molecules through the membrane if they can't diffuse directly through the phospholipid bilayer?
Proteins can act as channels or gates
500
What is the largest fiber of the cytoskeleton called and what is its function?
Microtubules, creates the highways inside the cell
500
Why is a phosphate molecule hydrophilic? (Be specific)
Because it is charged which makes it polar. Charged particles dissolve in water.
