What are the 2 parts of passive transport? |
*Diffusion *Facilitated diffusion *don't need energy |
|
|
Diffusion is? |
from areas of higher concentration to lower, across membrane, no energy needed |
|
|
Active transport |
*requires energy *often is transporting a molecule from an area of lower concentration to a higher one. *this is what allows a cell to maintain the molecules it need to perform its functions. Molecules like amino acids,glucose,protein etc. |
|
|
Diffusion |
*small inorganic molecules (nonpolar) *small polar molecules, water, etc. OSMOSIS
[It goes from high to low] |
|
|
OSMOSIS |
Diffusion of water across a selective permeable to another to make an equal concentration of two sides |
|
|
Isotonic solutions |
Have same number of solutes, (equal concentration) normal |
|
|
Hypotonic solutions |
Contains fewer solutes, (lower concentration - low solute) se infla |
|
|
Hypertonic solutions |
Contain more solutes then the intracellular fluid of a cell, (higher concentration - high solute) se encoje |
|
|
Exocytosis |
*Moving molecules outside the cell *requires energy |
|
|
Endocytosis |
Cell takes macromoleciles inside of the cell forming vesicles from the membrane in the reverse manner of exocytosis. |
|
|
Pinocytosis |
Brings in large portions of extracellular Fluid, (cell drinking) |
|
|
Phagocytosis |
Brings in large Solid items |
|
|
Exocytosis |
Outside . Requires energy |
