1. Myristoyl-CoA is a saturated fatty acid with 14 carbons
attached to coenzyme A. How many molecules of ATP would be
generated from the complete oxidation of a single molecule of
myristoyl-CoA? Important notes: Recall that the
investment of 2 ATP is required to generate Myristoyl-CoA from
myristate. Do not include these 2 ATP in your
calculations of ATP yield. Assume that each molecule of NADH
corresponds to 2.5 ATP synthesized, and each molecule of
FADH2 leads to 1.5 ATP...
Why is the liver unable to utilize acetyl-CoA for
gluconeogenesis? Why is this not a limitation for plants? Which
enzymes are we missing for this pathway?
In glycolysis, the conversion from pyruvate to acetyl CoA is
irreversible, but I found that during the synthesis of FA, acetyl
CoA can be synthesized to citrate -> OAA -> Malate
->pyruvate when Citric acid shuttle, why we cannot say that
pyruvate can turn back to acetyl CoA?
