Question

question
where is pyruvate dehydrogenase located?
answer
in the cytosol of prokaryotes and the intermembrane space in eukaryotes
in the cytosol of both prokaryotes and eukaryotes
in the mitochondrial matrix of eukaryotes but not in prokaryotes
in the cytosol of prokaryotes and the mitochondrial matrix of eukaryotes
i dont know yet

Explanation:

Pyruvate dehydrogenase is an enzyme complex that plays a key role in cellular respiration. In prokaryotes, which lack membrane - bound organelles, many metabolic enzymes are located in the cytosol. In eukaryotes, pyruvate dehydrogenase is located in the mitochondrial matrix. The mitochondrial matrix is the innermost compartment of the mitochondria, where the pyruvate dehydrogenase complex catalyzes the conversion of pyruvate to acetyl - CoA.

Answer:

In the cytosol of prokaryotes and the mitochondrial matrix of eukaryotes
