any process where molecules move from an area of high concentration without energy. diffusion, facilitated diffusion, and osmosis are examples

Question 20

facilitated diffusion

Answer 20

when a transport protein is used during the diffusion process

Question 21

integral protein

Answer 21

a protein used for transport that pass through the membrane

Question 22

peripheral protein

Answer 22

a protein that attaches to only one side of the membrane used for anchoring the cytoskeleton or carbohydrates

Question 23

carbohydrate tags/chains

Answer 23

chains of polysaccharides attached to the outside of a cell membrane. identify cell type and that it belongs in the body

Question 24

active transport

Answer 24

a process where molecules move from an area of low concentration to an area of high concentration. this process requires energy and a carrier membrane protein

Question 25

transport protein

Answer 25

a protein that spans the width of the plasma membrane that selects which molecule can travel through it

Question 26

endocytosis

Answer 26

a process where the plasma membrane wraps around a substance, forms a vesicle, and takes the substance into the cell

Question 27

exocytosis

Answer 27

a process where a vesicle binds to the plasma membrane and releases its contents outside of the cell
