Cell Processes For Homeostasis

Question 1

The cell membrane is also called the…

Answer 1

Plasma membrane

Question 2

The cell membrane is made up of the…

Answer 2

Phospholipid bilayer

Question 3

The phospholipids have heads that…

Answer 3

Attract water

Question 4

The phospholipids have tails that…

Answer 4

Repel water

Question 5

The head of a phospholipid is made up of a _ and _.

Answer 5

Alcohol, phosphate lipid

Question 6

The tails are made of chains of _.

Answer 6

Lipids

Question 7

Phospholipids move freely and let water and other simple molecules through. This is called_ _.

Answer 7

Simple diffusion because it doesn’t require energy. Mov s with the concentration(high to low)

Question 8

Cholesterol

Answer 8

Makes the membrane more fluid

Question 9

Proteins embedded in the phospholipid bilayer that…

Answer 9

Aid in diffusion and cell recognition.

Question 10

Another name for integral protein

Answer 10

Trans membrane proteins

Question 11

Integral protein

Answer 11

Goes all the way through the phospholipid bilayer.

Question 12

Perpieral Protein

Answer 12

Only on one side of the phospholipid bilayer.

Question 13

Carbohydrate glycoproteins

Answer 13

Name tags

Question 14

Osmosis

Answer 14

The diffusion of WATER through a selectively permeable membrane.

Question 15

Isotonic

Answer 15

Equal solute percentage

Question 16

Hypertonic

Answer 16

More solute outside the cell. Water moves out of the cell and it shrivels and dies.

Question 17

Hypotonic

Answer 17

More solute in the cell. Water goes into the cell and it swells and bursts.

Question 18

Endocytosis

Answer 18

Traps stuff and brings stuff in. (Active transport)

Question 19

Exocytosis

Answer 19

Releasing stuff outside (active transport)

Question 20

Facilitated diffusion

Answer 20

Like diffusion but a helper protein is needed.
