What does not influence the rate of diffusion of a chemical across plasma membrane

Answer 16

Amount of ATP

Question 17

What type of transport uses ATP to go against the concentration gradient

Answer 17

Active Transport

Question 18

If the solute concentration is greater inside of the cell than the outside, the movement of water via osmosis will be

Answer 18

Into cell cause water moves low to high concentration

Question 19

What transport process uses vesicles formed at cell membrane to take up extracellular substances and import them into cell

Answer 19

Endocytosis

Question 20

In this transport, a solute binds to a specific carrier protein on one side of the membrane. This binding induces a conformational change in the carrier protein that results in solute moving down its concentration gradient

Answer 20

Faciltiated diffusion

Answer 21

Simple diffusion; no assistance

Skeletal muscle

Answer 29

Attached to bones around entrance points of body, voluntary, long cylindrical and many nuclei

Question 30

Smooth muscle

Answer 30

Walls of major organs and pathways, regulate movement of materials through digestive tract or ducts and regulate blood flow in capillaries, involuntary, short spindle shaped and one nuclei

Solvent

Question 38

Diffusion concentration

Answer 38

High to low

Question 39

Osmosis differs from diffusion in that it requires a membrane that is

Answer 39

Selectively permeable

Question 40

A RBC placed in a HYPOTONIC solution will

Answer 40

plump and burst

Question 41

Crenation

Answer 41

Term to describe shrinking of RBC

Question 42

Material is transported out the cell through

Answer 42

Exocytosis

Question 43

How is diffusion, facilitated diffusion, osmosis and active transport are different

Answer 43

- Diffusion goes from high to low concentration and requires NO energy - Facilitated diffusion is the assistance of materials to go through the cell membrane with the help of transmembrane integral proteins like carrier/channel proteins (NO ENERGY) - Osmosis is the diffusion of WATER from low to high concentration and no energy used - Active transport is moving materials against their concentration gradient using ATP

Question 44

How is diffusion important to living cell

Answer 44

Small and non polar (no charge) molecules like CO2 and O2 can move in and out cell

Question 45

How is facilitated diffusion important for living cell

Answer 45

Helping materials that are harder to pass through the cell such as large molecule or ions like glucose to move in and out cell

Question 46

How is osmosis important for living cell

Answer 46

Cells can maintain proper water balance quickly and easily because of the unrestricted movement of water to their concentration gradient

Question 47

How is active transport important for living cell

Answer 47

Cells can maintain concentrations of molecules even when their concentration gradient does not favour such movements in and out cell (Sodium and potassium ions)

Question 48

How is phagocytosis important for living cell

Answer 48

Cells can engulf molecules that are too big to fit through carrier or channel proteins

Question 49

How is pinocytosis important for living cell

Answer 49

Cells can "Drink" large quantities of extracelula fluid to access dissolved substances that are not able to travel across membrane

Question 50

How is exocytosis important for living cell

Answer 50

Cells can eliminate unwanted material that are too big for carrier/channel proteins

Question 51

What would happen if a RBC is placed in water

Answer 51

The RBC would be surrounded by a hypotonic solution, where there is greater concentration in the cell than outside so there would be a net diffusion of water flowing in cell causing it to swell and eventually burst (lyse)

Question 52

What would happen if a RBC is placed in a highly concentrated salt solution

Answer 52

The RBC would be surrounded by a hypertonic solution, where there is lower concentration in the cell than outside so there would be a net diffusion of water flowing out the cell causing it to shrivel and die (plasmolysis/crenation)
