Cell structure and function

Question 1

What is the cell membrane made out of

Answer 1

Proteins and phospholipid

Question 2

Phosphate means hydrophilic or hydrophobic

Answer 2

hydrophilic

Question 3

movement of particles of a substance from where they are made, concentred to where they are less concentrated
maintain homestasis
energy is not required it is only a movement

Answer 3

diffusion

Question 4

this type of transport does not require energy, straight through bilayer
goes with concerted gradient
high concentration to low concentration

Answer 4

passive transport

Question 5

movement of substance across a membrane with help of transporting protein
high to low

Answer 5

facilitied diffusion

Question 6

movement of water across the bilayer

Answer 6

osmosis-passive transport

Question 7

concetration of solution are equal

Answer 7

isotonic

Question 8

solution with hyper concentration of water

water moving out

Answer 8

hypertonic

Question 9

solution with lower contration of water

water moving in

Answer 9

hypotonic

Question 10

requires energy-

goes against the concentration gradient

Answer 10

active transport

Question 11

what is ATP

Answer 11

energy used by all cells

adenine triphosphate

Question 12

exporting proteins from a cell by vesicles fusion with the cell membrane

Answer 12

exocytosis: active transport

Question 13

cells engulfs materials that are take into the cell vesicles that bud inward from the cell membrane

Answer 13

endocytosis: active transport
