It is carried by specific transporters (the negative charge on pyruvate won't allow it to diffuse) before being acted on by pyruvate dehydrogenase. I don't think these transports are named.

Acetyl CoA forms.
Immediately after pyruvate enters the mitochondrion, it is converted into acetyl-CoA through a process called pyruvate decarboxylation. This reaction is catalyzed by the pyruvate dehydrogenase complex, which also produces carbon dioxide as a byproduct and reduces NAD+ to NADH. Acetyl-CoA then enters the citric acid cycle (Krebs cycle) to continue cellular respiration and energy production.
Once pyruvate is transported into the mitochondrion, it undergoes decarboxylation, where one carbon atom is removed and released as carbon dioxide (CO2). This process is catalyzed by the pyruvate dehydrogenase complex, and the remaining two-carbon molecule, acetyl-CoA, is formed. Acetyl-CoA then enters the citric acid cycle (Krebs cycle) for further energy production. Additionally, during this conversion, NAD+ is reduced to NADH, which carries electrons to the electron transport chain for ATP synthesis.
Pyruvate oxidation takes place in the mitochondrial matrix. Here, pyruvate is converted into acetyl-CoA by the pyruvate dehydrogenase complex, which is a critical step in aerobic respiration.

After pyruvate is brought into the mitochondria, it undergoes a series of enzymatic reactions called pyruvate decarboxylation. In this process, pyruvate is converted into acetyl-CoA, which can then enter the citric acid cycle (also known as the Krebs cycle or TCA cycle) to produce energy in the form of ATP.

according to the Holt biology book of 2009, mitochondrion is no longer in use
glucose is changed into pyruvate
glucose is changed into pyruvate
The lactate is taken to the liver and converted back to pyruvate.
