What molecules are involved in pyruvate dehydrogenase and their functions?

Pyruvate dehydrogenase (PDH) are regulated by pyruvate dehydrogenase kinase (PDH-K) and PDH phosphatase. PDH-K effect on PDH is that it will inactivate PDH and PDH phosphatase will reactivate PDH.
PDH-K is regulated by energy surpluses (ATP, NADH) and energy deficits (ADP, NAD). So when there is an energy surplus, PDH-K will inhibit PDH, and vice versa.
PDH phosphatase will activate PDH and is upregulated by magnesium and calcium.

Which are products of pyruvate dehydrogenase?
Pyruvate dehydrogenase complex react with pyruvate to form acetyl-CoA
What enzyme is responsible for aerobic respiration?
There are very many enzymes involved. A few from glycolysis are: hexokinase and glucokinase, phosphohexose isomerase, phosphofructokinase, pyruvate kinase; from pyruvate decarboxylation are pyruvate dehydrogenase phosphatase and pyruvate dehydrogenase kinase; and a few from the Kreb's cycle are: aconitase, alpha-ketoglutamate dehydrogenase, succinate thiokinase, and fumarase.
Where can pyruvate dehydrogenase be found?
Mitochondria
Which enzyme is the most similar to Pyruvate dehyrogenase a citrate dyhydrogenase b malate dehydrogenase c succinate dehydrogenase d isocitrate dehydrogenase e alpha ketoglutarage dehydrogenase?
alpha-ketoglutarate dehydrogenase is most similar to pyruvate dehydrogenase as both are enzyme complexes made of 3 units
Where is pyruvate dehydrogenase complex located in prokaryotes?
in cyptoplasm of the prokaryotic cell

What is the function of dehydrogenase?
dehydrogenase is an enzyme which transfers hydrogen ions from a substrate to an activator.Example are activators are NAD+ and FAD+.
