|
Inhibition of phosphofructokinase-1 by ATP is an example of what kind of inhibition? |
Allosteric and Feedback inhibition |
|
A transcription factor must contain what kind of signal? |
Nuclear localization sequence |
|
Ubiquitination |
can affect proteins in many ways: it can signal for their degradation via the proteasome, alter their cellular location, affect their activity, and promote or prevent protein interactions. |
|
Proteasome |
Breaks down "garbage" protein Completely degrades it Different from protease which just hydrolyzes bond |
|
If a protein becomes denatured and inserted into the inner membrane of mitochondria: |
Choose answer: proton gradiant across inner membrane will dissipate (not ETC will cease) |
|
GAPDH - Glyceraldehyde 3 phophate dehydrogenase |
Catalyzes glyceraldehyde 3 phosphate ---> 1,3 biphosphoglycerate |
|

Western blot |
|
Southern Blot |
DNA |
|
Northern blot |
RNA |
|
Vasopressin |
Regulates fusion of aquaporins with apical membranes of collecting duct epithelial cells ADH - increase H20 permeability |
|
Apical membrane |
Membrane of polarized cells - surface of membrane that faces inwards to the lumen |
|
If bacteria enters the blood stream from the small intestine, which will be the first major organ that it will encounter |
LIVER -Blood from small intestine is transported first to liver, which regulates nutrient distribution and removes toxins form the blood |
|
How to find percent increase or decrease of two numbers |
|
|
Compared to the WT, a mutation resulting in the addition of a nucleotide (not effect stop codon) will result in: |
Both will have the same amino terminal, but different primary carboxyl terminal sequence (since another nucleotide is added) N->C |
|

|
Centromere vs centrosome |
Centromere: Part of chromosome that links sister chromatids Centrosome: Cell organelle, center for microtubule organization |
|
Kinetochore |

|
Microtubules originate from ________ for cellular transport |
Centrosome |
