Calculate the number of ATP produced (or consumed) by conversion
of Leu to acetoacetate using this overall conversion :
2 Leu → 3 acetoacetate + 2 NH3
(Hint: use the enzymes you learned for making ketone bodies at
the end)
Calculate the number of ATP molecules produced by complete
β−oxidation of the fourteen-carbon saturated fatty acid
tetradecanoic acid (common name: myristic acid).
THE ANSWER IS NOT 92!!!
What is the number of ATP and ATP equivalents that can be
produced via oxidative phosphorylation per cycle of the Citric Acid
Cycle (CAC), starting from pyruvate? B) What is the number of ATP
and ATP equivalents that can potentially be produced if Complex I
of the Electron Transport System (ETS) is inhibited? C) If Complex
II of the ETS is inhibited? D) If Complex III of the ETS is
inhibited? E) If Complex IV of the ETS is inhibited?
State if each of the following processes release or required
ATP: (ATP PRODUCED OR CONSUMED)
a. citric acid cycle
b. glucose forms two pyruvate
c. pyruvate forms acetyl CoA
d. glucose forms glucose-6-phosphate
f. First six reactions of glycolysis
how much ATP will be produced based only on the number of acetyl
coA units, from B oxidation of stearic acid? stearic acid is an 18
carbon, saturated fatty acid
(a)108ATP
(b) 148ATP
(c)18ATP
(d)27ATP
(2) which stage of the complete oxidation of glucose produces
the largest ATP yield?
(a)oxidation of decarboxylation
(b) glycolysis
(c) citric acid cycle
(d)anaerobic conditions
(3) reaction #7 of the citric acid involves the formation of a
secondary alcohol in malate from a double bond...
How many net ATP equivalents (including GTPs) would be produced
from the complete catabolism of a 16-carbon fatty acid in the
presence of oxygen (products can go through Kreb's, ETC, and ATP
synthase)?
I believe the answer is 129. Can you break down the step-by-step
process of this?
ATP synthesis in glycolysis substrate-level phosphorylation
The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one used to produce ATP during oxidative phosphorylation. Phosphorylation reactions involve the addition of a phosphate group to another molecule.
Sort the statements into the appropriate bin depending on whether or not they correctly describe some aspect of substrate-level phosphorylation in glycolysis.
