Lab 7 Quiz (for 10/23)

Question 1

Draw the basic structure of plasma membrane structure

Question 2

Passive Transport (ATP)

Answer 2

does not require energy (ATP)
- simple diffusion

Question 3

Active Transport (ATP)

Answer 3

requires additional energy (ATP)
- cotransport

Question 4

Diffusion

Answer 4

Movement of molecules from high to low region

Question 5

Facilitated vs Simple Diffusion

Answer 5

Facilitated Diffusion - molecules need help

Simple Diffusion - molecules go directly through membrane (no help)

Question 6

Diffusion rate depends on:

(affect rate)

Hint: 3

Answer 6

1. Diameter of the molecules, smaller moves faster
2. Temperature, the higher the temperature the faster the diffusion
3. Concentration gradient, greater the gradient the faster the diffusion

Question 7

Osmosis

Answer 7

Diffusion of H2O

Question 8

H2O moves where?

Answer 8

H2O moves towards side of membrane with more solute

Question 9

Hypertonic solution

Answer 9

water is leaving the cell
- loses water

Question 10

Hypotonic solution

Answer 10

water goes inside the cell
- gains water

Question 11

In animal cells… the cell shrinks in

Answer 11

Hypertonic solution

Question 12

In animal cells… the cell swells and may lyse in

Answer 12

Hypotonic solution

Question 13

In animal cells… the cell remains normal in

Answer 13

Isotonic solution

Question 14

What moves from high concentration to low concentration

Answer 14

Passive Transport

Question 15

What moves from low concentration to high concentration

Answer 15

Active Transport
