PDK1 (pyruvate dehydrogenase kinase 1) is an enzyme which inactivates the pyruvate dehydrogenase by phosphorylating it using an ATP molecule<span>.
</span><span>PDK1 (phosphoinositide-dependent protein kinase-1) acts by catalyzing the phosphorylation of Thr-229 (threonine at position 229 in pyruvate dehydrogenase).
This phosphorylation is </span><span>synergistic</span> with the phosphorylation of C-terminal Thr-389, but this one is not done by the PDK1.
Answer:
C Differences among temperature, air pressure, and density
Explanation:
Classification of the atmosphere layer will be different based on the temperature, air pressure, and density. Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.
DNA being placed with DNA polymerase and nucleotides and resulting in new copies is not an opinion or inference because the fact is, new more DNA was found in the test tube after adding the enzymes and nucleotides than before the addition. DNA sequencing of the new copies would have shown that the sequences of the new DNA are identical to the original DNA that was first placed in the test tube. Also, other experiments would have shown that adding other different kinds of molecules or enzymes does not, in fact, produce new strands of the original DNA, nor should it be able replicate the DNA at all.
