Stores energy
Insulation
Part of Cell Membrane
Explain the function of phospholipids in the cell membrane.
Acts as the barrier.
Explain what passive transport is.
Transport that requires no energy input.
Explain what active transport is.
Transport that requires ENERGY
Which type of transport involves water movement from high to low concentration?
Passive Transport- Osmosis
Which part of a phospholipid is Hydrophilic?
Phosphate Head
Which 2 components are used to signal to your immune system?
How does a substance flow during passive transport? (What concentration to what concentration)
High to low.
Which type of cell membrane component is needed to run the sodium-potassium pump so your brain can work?
Carrier Protein
What happens when there is a higher concentration of water on the outside of the cell?
Cell Swells
Name one example of an unsaturated fat and one example of a saturated fat.
Unsaturated: Any oil (except coconut)
Saturated: Butter, Coconut Oil, Lard
Explain the difference between peripheral and integral proteins.
Peripheral is NOT all the way through the membrane
Integral IS all the way through the membrane
Which kind of passive transport involves larger molecules and needs a channel protein?
Facilitated Diffusion
Which process would happen if your cell wants to bring in a large piece of protein?
Endocytosis/Phagocytosis
Please give the tonic state and what would happen to the cell:
Inside of the cell: 63% H2O, 37% NaCl
Outside of the cell: 63% H2O, 37% NaCl
Isotonic- nothing would happen
Name ALL THREE elements found in lipids.
Carbon, Hydrogen and Oxygen (CHO)
Materials need to move through the WHOLE membrane
Which type of passive transport would involve oxygen getting into your cell?
Diffusion
Which process would happen if your cell wants to get rid of cellular garbage?
Exocytosis
Please give the tonic state and what would happen to the cell:
Inside of the cell: 78% H2O, 22% NaCl
Outside of the cell: 53% H2O, 47% NaCl
Hypertonic- cell shrinks
Provide the structural difference between unsaturated fat and saturated fat.
Unsaturated: contains double bonds
Saturated: contains no double bonds
Explain the difference between carrier proteins and channel proteins.
Carrier: requires energy
Channel: no energy required
How would water enter or exit the cell?
Osmosis
Which process would happen if your cell wants to bring in a bunch of water AGAINST normal concentration gradient flow?
Pinocytosis
Please give the tonic state and what would happen to the cell:
Inside of the cell: 88% H2O, 12% NaCl
Outside of the cell: 91% H2O, 9% NaCl
Hypotonic- cell swells
