Cholesterol

Question 14

Acts as if he sells identity markers. Cell recognition

Answer 14

Carbohydrates

Question 15

What are three functions of the cell membrane

Answer 15

– Outer boundary
– Selectively permeable
– Responds to changes

Question 16

The movement of molecules from regions of higher to regions of lower concentration. Nonpolar substances

Answer 16

Diffusion

Question 17

What kind of substances need proteins to get through a cells membrane

Answer 17

Polar or ionic substances

Question 18

Membrane water channels

Answer 18

Aquaporin

Question 19

A solution having the same total solute concentration of the solution with which it is compared

Answer 19

Isotonic

Question 20

A solution with a greater solute concentration than plasma

Answer 20

Hypertonic

Question 21

When the concentration of a solution is lower than the inside of a cell water enters the cell

Answer 21

Hypotonic

Question 22

When the concentration of a solution is higher than the inside of the cell water leaves the cell

Answer 22

Hypertonic

Question 23

Passive transport of polar or ionic molecules across a biological membrane using carrier proteins

Answer 23

Facilitated diffusion

Question 24

Directly uses ATP to transport molecules across a membrane.

Answer 24

Primary active transport

Question 25

What is the sodium to potassium ratio in a sodium potassium pump

Answer 25

Three sodium go out for every two potassium that comes in

Question 26

Energy is used to transport molecules across a membrane. No ATP used. Relies on electrochemical potential difference

Answer 26

Secondary active transport (co-transport)

1 Glucose moves L-H

Both go in same direction (into cell)

Answer 27

Symport

Ion moves H-L

Ion moves L-H

Three sodium ions in – one calcium out

Answer 28

Antiport

Question 29

Bringing something the cell

Answer 29

Endocytosis
