Lesson 3 - Physicochemical properties of the cell

Question 1

Substance move across a cell membrane without energy by the cell

Answer 1

Passive Transport

Question 2

Passive Transport

Answer 2

transport that is not ATP driven, high to low concentration

Question 3

Types of passive transport

Answer 3

Diffusion, Osmosis, Facilitated Diffusion

Question 4

Osmosis, types of solution

Answer 4

Isotonic, Hypotonic, Hypertonic

Question 5

Diffusion

Answer 5

net movement of particles along a concentration gradient from an area of high concentration to low concentration

Question 6

Osmosis

Answer 6

net movement of water by diffusion through a selectively permeable membrane

Question 7

Isotonic

Answer 7

equal rate movement of water molecules in and out of the cell

Question 8

Hypotonic

Answer 8

Outside solute concentration is lower than the inside solute concentration

Question 9

Water moves into the cell

Answer 9

Hypotonic

Question 10

Hypotonic ____

Answer 10

swells

Question 11

Hypertonic

Answer 11

Outside solute concentration is higher than the inside solute concentration

Question 12

Water moves out of the cell

Answer 12

Hypertonic

Question 13

Hypertonic _______/______

Answer 13

plasmolyzed/shrinks

Question 14

Facilitated Diffusion

Answer 14

Uses transport protein to move to high to low concentration

Question 15

Molecules move through a transport protein but now uses energy to move against their concentration gradient

Answer 15

Active transport

Question 16

Active tranport

Answer 16

ATP driven, requires energy, low to high

Question 17

Types of active transport

Answer 17

Primary active transport and Secondary active transport

Question 18

Primary Active Transport

Answer 18

directly use energy

Question 19

Example of primary active transport

Answer 19

sodium potassium pump moves sodium ion, using the energy of ATP hydrolysis to establish a concentration gradient

Question 20

Secondary Active Transport

Answer 20

does not directly use ATP, relies on the energy stored in the form of ion gradient created by the PAT

Question 21

Bulk transport is also known as

Answer 21

Vesicle transport

Question 22

Bulk transport

Answer 22

movement of large quantities of material into or out of cells using membrane-bound vesicle

Question 23

Types of bulk transport

Answer 23

Endocytosis and exocytosis

Question 24

Endocytosis

Answer 24

engulf extracellular material/going inside

Question 25

Types of endocytosis

Answer 25

Phagocytosis, Pinocytosis, Receptor

Question 26

Cell eating

Answer 26

Phagocytosis

Question 27

Cell drinking

Answer 27

Pinocytosis

Question 28

Receptor

Answer 28

takes in molecules that bind to receptors on the cell surface

Question 29

Exocytosis

Answer 29

Expel extracellular materials into extracellular space/going outside

Question 30

Which specimen diffused father?

Answer 30

Potassium permanganate, due to its smaller molecular size

Question 31

How does the molecular weight of congo red, safranin and potassium permanganate affect the rate of diffusion?

Answer 31

If a molecule has a lower molecular weight, less effort to move through. If larger molecular weight, more resistance due to its size and slow down the rate of diffusion
