chapter 5 the working cell

Question 1

selectively premeable plasma membrane

Answer 1

allows some stuff to pass through

Question 2

2 types of transport

Answer 2

passive and active

Question 3

passive

Answer 3

cell uses no energy as it moves down concentration gradient

Question 4

3 types of passive transport

Answer 4

diffusion, osmosis, and facilitated diffusion

Question 5

diffusion

Answer 5

movement of high to low concentration

Question 6

what affects diffusion ?

Answer 6

steep concentration, temp, molecular size, presence of electric and pressure gradient

Question 7

Osmosis

Answer 7

same thing but with water where you have hyper ,hypotonic, or isotonic conditions

Question 8

hypertonic

Answer 8

where 1 out of 2 has a high concentration solute

Question 9

hypotonic

Answer 9

1 out of 2 has a low concentration solute

Question 10

isotonic

Answer 10

2 have equal concentration

Question 11

how do plants encourage osmosis

Answer 11

the vacuoles becomes hypertonic that encourages water to come in

Question 12

active

Answer 12

cell uses energy to move gradient

Question 13

protein mediated transport ( facilitated diffusion)

Answer 13

moves down concentration gradient via protein

Question 14

exocytosis and endocytosis

Answer 14

transport material in bulks

Question 15

endocytosis 3 types

Answer 15

Phagocytosis, pinocytosis, receptor mediated endocytosis

Question 16

phagocytosis

Answer 16

soil matter in bulk (eating )

Question 17

pinocytosis

Answer 17

Liquid matter in bulk ( drinking )

Question 18

exocytosis

Answer 18

substances released by cell

Question 19

signal transduction pathway

Answer 19

series of molecular reactions where a signal on cells surface tiggers specific responses within cell

Question 20

energy

Answer 20

capacity to do work

Question 21

2 types of energy

Answer 21

kinetic and potenial

Question 22

cellular respiration

Answer 22

energy releasing breakdown of food molecules
