Cell Membrane

Question 1

hydrophilic

Answer 1

water loving

Question 2

hydrophobic

Answer 2

water fearing

Question 3

integral proteins

Answer 3

integrated through the entire membrane

Stuck inside the membrane

Question 4

peripheral proteins

Answer 4

sits on the outside of the membrane

Question 5

Types of integral proteins

Answer 5

• channel proteins
• carrier proteins
• glycoproteins

Question 6

passive transport

Answer 6

transport of molecules across the membrane requiring no energy
goes DOWN concentration gradient

Question 7

active transport

Answer 7

transport of molecules across the membrane requiring energy
goes UP concentration gradient

Question 8

simple diffusion

Answer 8

goes right through the membrane

Question 9

facilitated diffusion

Answer 9

Passive moment of molecules across the concentration gradient
Needs channel mediated or carrier mediated

Question 10

channel mediated transport

Answer 10

the movement of small ions across the plasma membrane through water-filled protein channels

Question 11

carrier mediated transport

Answer 11

The type of transport in which proteins bind to ions or substrates and carry them across the plasma membrane

Question 12

protein pump

Answer 12

transport proteins that require energy to do work

Question 13

leak channels

Answer 13

channels that are always open and allow ions to move along their gradient

Question 14

gated channels

Answer 14

A protein channel in a cell membrane that opens or closes in response to a particular stimulus.

Question 15

phospholipid

Answer 15

1. Phosphate head (water loving- hydrophilic)
2. Glycerol backbone (water fearing- hydrophobic)
3. Fatty acid tails
