|
what are the types of integral proteins? |
ion channel, carrier, receptor, enzyme, linker |
|
|
what is the function of an ion channel? |
forms pore where ions can flow across the membrane |
|
|
what is the function of a carrier? |
transports a substance across the membrane by going through a shape change |
|
|
what is the function of a receptor? |
to recognize a specific ligand, and alters the cell's function |
|
|
what is the function of an enzyme? |
catalyzes reactions inside/outside the cell |
|
|
what are the types of peripheral proteins? |
enzymes, linker |
|
|
what is the function of a linker? |
anchors filaments inside/outside p-membrane; provides shape and structure for the cell |
|
|
what type of protein is a glycoprotein? |
cell identity marker |
|
|
how does a Na+/K+ pump work? |
3 Na+ from the cytosol bind to receptors in protein this triggers ATP hydrolysis = ATP knocks of a phosphate, then becoming ADP the fallen phosphate binds to the protein, causing a shape change the Na+ is exposed to the extracellular fluid & binds to a protein 2 potassium from extracellular fluid bind to the protein, this triggers the phosphate to fall off, causing the protein to go back to normal |
|
|
what kind of transport is a Na+/K+ pump? |
primary active transport |
