Cells 2 Flashcards
Only certain materials can pass through a surface.
Semipermeable
What the cell membrane is made out of.
Phospholipid Bilayer
Something that is polar, the head of a phospholipids.
Hydrophilic
Something that is nonpolar, the tails of phospholipids.
Hydrophilic
The model of a cell membrane and its components.
Fluid Mosaic Model
Transportation of materials through the cell membrane without using energy. High –> Low
Passive Transport
Transportation of materials through the cell membrane using energy. Low –> High
Active Transport
Transport of materials from high to low naturally over the cell membrane.
Simple Diffusion
The diffusion of water.
Osmosis
When materials are equally spread out inside and outside the cell.
Equilibrium
The way the materials move in a cell. Low to High or High to Low.
Concentration Gradient
When there are more solutions outside the cell than inside the cell.
Hypotonic Solution
When there are equal amounts of solutions inside and outside of a cell.
Isotonic Solution
When there are more solutions outside the cell than inside the cell.
Hypertonic Solution
Swollen, when a cell contains too much water and solutions inside that it becomes to large in volume pushing the cell membrane.
Turgid
When materials are being moved through the cell membrane with the help of proteins.
Facilitated Diffusion
A open protein that helps materials get past the cell membrane.
Channel Protein
A protein that helps water get through the cell membrane.
Aquaporin
Adenosine-Triphosphate, a material in a cell that is used to activate proteins and it is used as energy for cells.
ATP
