Answer 2

Both polar and non polar regions

Question 3

What is the membrane permeable to

Answer 3

Lipid soluble substances (gases, ethanol, water, urea (partial))

Question 4

What is the cell membrane impermeable to

Answer 4

Ionic and polar substances (amino acids, ATP, glucose 6-phosphate)

Question 5

Three main types of transport

Answer 5

Passive diffusion
Facilitated diffusion
Active transport

Question 6

Fick’s law

Answer 6

Rate of diffusion = D (diffusion conc) x A (area) x concentration gradient
