Transportation Across Membrane

Question 1

Solute

Answer 1

part that dissolves
lower quantity substance in mixture

Question 2

Solvent

Answer 2

will hold dissolved solute
higher quantity substance in mixture

Question 3

solution

Answer 3

liquid mixture where solute is uniformly distributed within solvent

Question 4

Diffusion

Answer 4

movements of particles from an area of high concentration to low concentration

Question 5

Factors affecting diffusion

Answer 5

Temperature, concentration gradient, surface area

Question 6

Osmosis

Answer 6

water molecules move through semi-permeable
(similar to diffusion)

Question 7

Passive Transport

Answer 7

diffusion in the same direction as the concentration gradient (no energy)

Question 8

Active Transport

Answer 8

diffusion against the concentration gradient
requires energy

Question 9

Endocytosis

Answer 9

enclosing matter & bringing it in

Question 10

Exocytosis

Answer 10

bringing out - releases contents to extracellular fluid

Question 11

Isotonic

Answer 11

equal amount of things going out and in

Question 12

Hypotonic

Answer 12

lots of solute, water will attempt to go into the cell, cell will get big

Question 13

Hypertonic

Answer 13

water trying to get out, cell will shrivel

Question 14

Homeostasis

Answer 14

steady state that results from maintaining near-constant conditions in the internal environment
