JW Flashcards
Ubiquitination is the ____ pathway
degradation
Oxidation number of Group 1A
+1
Oxidation number of Group 2A
+2
Oxidation number of Halogens
usually -1, positive with Oxygen
Oxidation number of an element by itself
0
Oxidation number of a monatomic ion
ion charge
Oxidation number of H
Oxidation number of Oxygen
Oxidation number of Flourine
Sum of oxidation numbers for a neutral compound
0
Sum of oxidation numbers for a polyatomic ion
ion charge
ADP + Pi is more disordered than ATP due to the
higher energy content in the three phosphate groups of ATP.
What states are not included in Keq (equilibrium constant)?
Pure solids and pure liquids, including solvents
A solution used to calibrate spectrophotometry, IR spectroscopy, chromatography, and fluorimetry
blank solution
Molecules with the same molecular formula but different structure/arrangement of atoms
Isomers
Molecules with the same molecular forum but display different connectivity of their atoms
Constitutional (or structural) isomers
Equation for power
P = E/t
CO2 (g) is more soluble in water than O2 (g) meaning that more O2 (gas)
will remain in gas form which will increase the pressure in a tube
The general molecular formula of esters
R-COO-R’ where R and R’ are alkyl groups (hydrocarbon chain)
Function of lactate dehydrogenase
catalyzes the conversion of pyruvate (a three carbon molecule) into lactate (a three carbon molecule) during anaerobic respiration.
A cellular process that produces energy (ATP) in the absence of oxygen
anaerobic respiration
Vitamin B3 (niacin) functions as a precursor for the redox coenzymes
NAD and NADP
Which coenzyme does lactate dehydrogenase use to convert pyruvate to lactate?
NAD, accepting a hydrogen atom making it NADH.
Niacin (vitamin B3) is the precursor to NAD
Structure of acyl functional group
Structure of isobutyl functional group
An organometallic compound with the general formula RMgX where R is an organic group, typically an alkyl (like isobutyl) or aryl (like benzyl) group, magnesium, and a halogen
Grignard reagent
The inhibitor binds to the same active site as the substrate, preventing the substrate from binding
competitive
The inhibitor binds to the enzyme-substrate complex, not the free enzyme
uncompetitive inhibition
Inhibitor that reduces the enzyme’s activity regardless of substrate concentration
noncompetitive inhibition
A type of enzyme inhibition where the inhibitor can bind to the enzyme in two ways, exhibiting both competitive and noncompetitive inhibition
mixed inhibition
