Nextstep 3 Biochem Flashcards
Phosphatase usually does? Whereas kinases?
Inhibits
Kinases activate
Electrons carriers can be?
Mobile and hydrophobic or immobile and water soluble.
During hyperventilation?
CO2 is lost and increased O2 happens. Loss of CO2 increases blood pH. Loss of CO2 is related to increased hemoglobin affinity for O2
What’s the definition of a lysogenic virus?
Lysogenic viruses alter nuclear DNA, but it not activated for several generations.
Triglycerides are composed of?
One glycerol molecule and three fatty acids.
Adenine and Guanine are?
Whereas thymine and cytosine are?
Purines two ring structures
Pyrimidines sing ring structures
Sn2 are favored by?
Polar aprotic solvents such as acetone or DMSO.
What is the kinectic energy of a photoelectron produced in the energy meter of a PAC devise when the frequency of an incident photon that is not absorbed is f=5•10^15 Hz and h= 4.1•10^-15eVs
detector work function equals to 3.4eV
You have to take into account the work utilized by the detector as well
5•10^15 Hz 4.1•10^-15eVs - 3.5eV = 17.1 eV
SN1 type of substitutions are most likely to happen when?
On the most stable (tertiary) carbocations.
