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
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 the most similar to Pyruvate dehydrogenase because both are part of the α-ketoglutarate dehydrogenase complex, involved in the citric acid cycle and share structural and functional similarities.
Where is pyruvate dehydrogenase complex located in prokaryotes?
In prokaryotes, the pyruvate dehydrogenase complex is located in the cytoplasm.
What are the protein substances required to break down pyruvate?
Enzymes that are involved in the breakdown of pyruvate include pyruvate dehydrogenase complex (PDC) and pyruvate carboxylase. These enzymes are crucial in converting pyruvate into acetyl-CoA to enter the citric acid cycle for further energy production.
Where can pyruvate dehydrogenase be found?
Pyruvate dehydrogenase is typically found in the mitochondria of eukaryotic cells. It plays a critical role in the conversion of pyruvate into acetyl-CoA, a key step in the process of aerobic respiration.

What is the function of dehydrogenase?
Dehydrogenase enzymes catalyze the removal of hydrogen atoms from a substrate molecule. This is an important step in various metabolic processes as it helps in transferring electrons and energy between molecules.
Which process involved in cellular respiration does not yield any high energy phosphate bonds?
Pyruvate dehydrogenase complex
What enzyme converts pyruvate into acetyl-CoA?
The enzyme that converts pyruvate into acetyl-CoA is pyruvate dehydrogenase. This multienzyme complex is responsible for catalyzing the conversion of pyruvate into acetyl-CoA, which is a key step in the metabolism of carbohydrates to produce energy.

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.
