transport of materials

Question 1

osmotic equalibrium

Answer 1

concentrations inside and out of the cell are the same

Question 2

plasma membrane

Answer 2

selectively permeable membrane that allows solutes and waste to move in and out of the cell

Question 3

passive transport

How can it be increased

Answer 3

movement of materials when no energy is used -increased by high conc gradient, small molecule size, higher temperatures

Question 4

diffusion

Answer 4

movement from an area of high concentration to an area of low concentration

Question 5

osmosis

Answer 5

movement of WATER across a semi permeable membrane

Question 6

facilitated diffusion

Answer 6

movement of larger molecules/ions through a protein channels or carrier proteins embedded in plasma membrane

Question 7

active transport

Answer 7

requires energy (ATP) to move materials in and out of cell

Question 8

pinocytosis

Answer 8

uptake of liquids by wrapping membrane around droplet

Question 9

phagocytosis

Answer 9

uptake of solid particles by engulfing by cells

Question 10

ion pumps/ carrier proteins

Answer 10

energy is used to change shape of carrier protein channel to pump ions against concentration gradients

Question 11

passive vs active transport

Answer 11

passive: no ATP required, transport WITH conc gradient
active: needs ATP, AGAINST con gradient
