Phospholipid
|
Has a head and fatty acid legs. The head is hydrophilic and the feet are hydrophobic. They are considered antipathy since they are polar and non-polar
|
|
Lipid Saturation |
unsaturated and saturated
|
|
Cholesterol
|
increases the fluidity of the membrane, prevents them from forming solid structures
|
|
Lipid Rafts
|
Similar lipids stick together and move through there together
|
|
Transporter
|
move things in and out of the cell
|
|
Receptor
|
will bind to molecules and instead of moving it through it just relays a message into the cell
|
|
Enzyme |
can be involved in chemical reaction |
|
Anchor
|
anchoring a cell to another cell or to a surface
|
|
Integral
|
they are in the membrane
|
|
Peripheral
|
outside of the membrane, hang out on the surface of the membrane
|
|
Transmembrane
|
they fully cross the membrane
|
|
Diffusion
|
high concentration to low concentration, passive movement, random movement of molecules- molecules are constantly moving
|
|
Facilitated Diffusion
|
proteins move things across the membrane, like larger particles
|
|
Osmosis
|
the diffusion of water across the membrane
|
|
Primary Transport
|
|
|
Secondary Transport
|
have blue protons are pumped out through primary active transport and that is electrochemical gradient where we ahve more on the outside so they transport "orange squares" to the outside. It is not using energy it is a reaction to primary transport
|
|
Electrochemical Gradient
|
the difference of charged molecules on the outside and the inside of the cell. The inside is usualy more negatively charged than the outside. Creates a lot of potential energy.
|
|
Contrast how cells with and without a cell wall maintain their shape.
|
Cells have a cytoskeleton that can help them maintain their shape. Plant cells have vacuoles and if the vacuoles fill up with water it puts pressure on the cell membrane. A normal cell/ a cell without a cell membrane, could potentially burst.
|
|
Exocytosis
|
things exiting the cell
|
|
Endocytosis
|
the cell will surround the molecules (whatever that may be) and bring them to the inside
|
|
Nucleus
|
stores genetic material
|
|
Rough ER
|
|
|
Smooth ER |
makes lipids |
|
Golgi Apparatus |
involved in modifying and labeling our proteins. Sometimes referred to as the post office. It labels them and tells them where to go.
|
|
Lysosomes
|
involved in breaking down molecules or "digesting" the molecules
|
|
Mitochondria
|
where we make energy
|
|
Chloroplasts
|
Used for photosynthesis |
