Chapter 3-Cells

Question 0

Understand how lipid bilayer is formed due to the phospholipids

Answer 0

Has a hydrophilic side that is attracted to water and links together sticking outwards. There is a hydrophobic side that is the inside of the layer

Question 1

What makes up plasma membrane?

Answer 1

Lipid Bi-Layer
Cholesterol
Glycolipids
Protons

Question 2

6 functions of membrane proteins

Answer 2

Transport
Maintain Cell Shape
Enzyme Activity 
Intercellular Joining
Cell-Cell Recognition

Question 3

Active and Passive transport

Answer 3

Passive
-no energy(atp) needed
Ex: simple & facilities diffusion

Active
-energy(atp) needed
Ex: primary & secondary

Question 4

Simple and Facilitated Diffusion

Answer 4

Simple
-no polar and lipid soluble substances dissolve directly through lipid bilayer

Facilitated
-transports proteins

Question 5

Channel and Carrier Protiens

Answer 5

Channel: water filled

Carrier: carries across membrane

Question 6

Isotonic, hypotonic, and hypertonic

Answer 6

Isotonic: same amount of concentration as cells and blood

Hypotonic: lower amount of concentration than cells and blood

Hypertonic: higher concentration than us found in normal cells and blood

Question 7

Primary and Secondary Active Transport

Answer 7

Primary: directly uses ATP to transport

Secondary: uses energy in other forms than ATP.
