Transport Proteins
|
The proteins that control the movement of substances through the membrane.
|
|
|
Receptor Proteins
|
They are the binding sites for specific messenger molecules that signal the cell to begin or to stop some metabolic activity.
|
|
|
Phospilid Bilayer
|
A lipid arranged in a double layer that consists of a phosphate group and two fatty acids.
|
|
|
Hydrophobic tail
|
The part of the lipid that doesn't love water
|
|
|
Hydrophilic head
|
The part of the lipid that loves water
|
|
|
Hypotonic Solution
|
The solution that contains a lower concentration of dissolved substances than the cell.
|
|
|
Hypertonic Solution
|
It contains a higher concentration of dissolved substances than the cell.
|
|
|
Isotonic Solution
|
The solution has the same concentration of dissolved substances as the living cell placed in it
|
|
|
Equilibrium
|
Situation where the molecules are of equal concentration out of the cell vs inside the cell.
|
|
|
Facilitated Diffusion
|
A process by which certain molecules diffuse quickly across the cell membrane without using ATP.
|
|
|
Contractile vacuole
|
The vacuole that contains excess water from the cell.
|
|
|
Active Transport
|
The type of transport that goes from a low to high concentration.
|
|
|
Passive Transport
|
The type of transport that goes from a high to low concentration.
|
|
|
Diffusion
|
The passive transport of molecules.
|
|
|
Osmosis
|
The diffusion of water.
|
|
|
Phagocytosis
|
The process by which large particles or small organisms are ingested into a cell.
|
|
|
Pinocytosis
|
The process by which liquids or very small particles from the surrounding medium are taking into a cell by the formation of a vesicle.
|
|
|
Turgor Pressure
|
The pressure exerted by water inside the cell against the cell wall.
|
|
|
Osmotic Pressure
|
The increase in pressure resulting from the flow of water in osmosis.
|
|
|
Big Molecules
|
Protein, Starch, and Lipids
|
|
|
Small Molecules
|
Amino acids, sugar, fatty acids and a glycerol, and glucose.
|
|
|
ATP- Adenosine Triphosphate.
|
The energy used to move molecules from a low to high concentration for active transport.
