|
Cytoplasm |
Interior contents of a cell, gel inside the membrane. |
What is inside of life's building blocks. ______ part of a cell. |
|
|
Phospholipid |
A group of fatty compounds, where the head faces outward and the tail is inward. |
Polar faces out, nonpolar faces in. Makes up part of the cell membrane. |
|
|
Phosphilipid Bilayer |
A group of phospholipids that make up part of the cell membrane. |
Makes up the cell's _______? A group of nonpolar and polar whats? |
|
|
Polar |
A molecule with an uneven charge on one side. |
AKA Dipole Asymmetrical |
|
|
Nonpolar |
A symmetric molecule with even charges on both ends. |
Can get through the cell membrane, small. Symmetrical. |
|
|
Transport Proteins |
Works with the bilayer in order to let necessary large polar molecules and ions into the membrane. |
Doesn't transport nonpolar molecules. Some come in, needs to let them out. |
|
|
Selective Permeability |
A function of the cell membrane that makes it so that only certain molecules can cross. |
It is a selective gateway. Only nonpolar. |
|
|
Glycoprotein |
A protein and a sugar combined to be a chemical receptor. |
Sugar + ? It is a part of the bilayer |
|
|
Glycolipid |
A lipid and a sugar combined to form a receptor molecule. |
Sugar+??? It's in the name. |
|
|
Fluid Mosaic Model |
The model of flexible plasma cell membranes. |
The outside of the cell. The cell made up of what? |
|
|
Concentration Gradient |
When there is an inequality in the concentration of molecules across an area. |
What happens when you spray perfume around a room? Who is the last to smell it and why? |
|
|
Diffusion |
When particles are spread equally across an area. |
Surface area. The end result of concentration. |
|
|
Osmosis |
Usually involved in the diffusion of water, and allows solvents into the cell membrane. |
Involved with water in some way. Allows certain things into the cell membrane. |
|
|
Turgor |
When the cell is so full that it becomes rigid, keeping the plant cell wall sturdy. |
Plants have it Fills like water balloon. |
|
|
Isotonic |
When there is the same level of water concentration in two solutions, or the same osmotic pressure. |
Equal levels of what? Similar pressure |
|
|
Hypotonic |
A solution with a lower salt concentration than others, causing water to flow in. |
Lower levels of water Has to do woth pressure |
|
|
Hypertonic |
When there is a higher osmotic pressure in a fluid. |
____ Osmotic pressure Higher levels of water |
|
|
Passive Transport |
Movement of molecules and biochemical substances without energy usage. |
What does passive mean? It is the opposite of active transport. |
|
|
Active Transport |
The movement of biochemical substances and molecules that requires energy and enzymes. |
Free what is required? It is a transportation that requires fuel? |
|
|
Facilitated Diffusion |
The use of carrier proteins to transport substances across the cell membrane. |
A result of selective permeability. Result of active transport. |
|
|
Endocytosis |
When the cell membrane folds inward to ingest a substance into the cell. |
Endo means what? Opposite of exocytosis |
|
|
Exocytosis |
When a substance is expelled from the cell membrane through a hole made in it. |
Exo means what? Opposite of endocytosis |
