Exam 1 (Review PPT's) Flashcards
D vs. L Sugars are _______ images
mirror
D/L is determined by the location of _____ group, most ______ to ketone
-OH; distal
L sugars
-OH is on the left
D sugars
-OH is on the right
Fermentations consumes pyruvate under what type of conditions?
anaerobic
Glycolysis is the primary mechanism for?
ATP production
Breakage of phophoanhydride bonds eliminates:
replusion between negative charges
Pyruvate is being reduced to what in fermentation?
lacate
In an enzyme, allosteric regulation effects:
substrate binding (Km), not Vmax
Competitive inhibition allows the inhibitor binds to:
active site
can competitive inhibition be overcome?
Yes, when there is enough substrate
Competitive Inhibition effects what in a an enzyme?
Increased Km
Unchanged Km, Vmax decreased
Noncompetitive Inhibitor
Can noncompetitive inhibition be overcome?
No.
Pyruvate Dehydrogenase Complex is required for:
krebs cycle to occur
E1: Pyruvate Dehydrogenase
remove carbon and produce CO2
E2: Dihydrolipoyl transacetylase
take two carbon and link to acetyl-CoA
E3: Dihydrolipoyl dehydrogenase
produce NADH by reduction reaction
Flow of protons through what drives conformational changes required for ATP synthesis and release of ATP by causing rotation of y subunits
F0
condensation reactions _____ energy
release
Km tells us:
how well the substrate and enzyme are binding
X-axis
Km
Y-axis
Vmax
