receptors
transport
enzymes
maintenance of structure
communication

Question 7

osmosis with no diffusion will lead to

Answer 7

change in cell volume

Question 8

osmolarity definition

Answer 8

total number of particles per L

both penetrating and non penetrating

Question 9

tonicity definition

Answer 9

number of non penetrating particles in solution

Question 10

osmolarity of plasma and cells

Answer 10

300 mOsmol/l

Question 11

1M of NaCl osmolarity

Answer 11

2 osmol/l

Na and Cl split

Question 12

Answer 12

Na+ and Cl-

Question 13

non penetrating molecules in ICF

Answer 13

k+

Question 14

example of a freely penetrating particle

Answer 14

urea

Question 15

solutions with same total number of solute particles as normal ECF are

Answer 15

isosmotic

Question 16

solutions with fewer total number of solute particles as normal ECF are

Answer 16

hyposmotic

Question 17

solutions with more total number of solute particles as normal ECF are

Answer 17

hyperosmotic

Question 18

solution with the same amount of non penetrating molecules as normal ECF

Answer 18

isotonic

Question 19

solution with fewer amount of non penetrating molecules as normal ECF

Answer 19

hypotonic

Question 20

solution with a larger amount of non penetrating molecules as normal ECF

Answer 20

hypertonic

Question 21

isosmotic can be

Answer 21

hypotonic and isotonic

Question 22

hyperosmotic can be

Answer 22

hypertonic, isotonic or hypotonic

Question 23

hyposmotic can be

Answer 23

only hypertonic

Question 24

tonicity of ECF

Answer 24

300- same as osmolarity as Na and Cl are the main molecules in ECF and are also the non penetrating particles

Question 25

cells in hypotonic solutions will

Answer 25

swell- water **enters** down chemical gradient less tonic more water in solution

Question 26

cells in a hypertonic solution will

Answer 26

shrink- water **leaves** down chemical gradient more tonic less water in solution
