When the pyruvate molecule enters the mitochondira it loses ________________.

Homework Answers

Answer #1

When pyruvate molecule enters the mitochondria it loses one carbon atom (with the release of carbon dioxide)

The transport of pyruvate into the mitochondria is via the transport protein pyruvate translocase . Pyruvate translocase transports pyruvate in a support fashion with a proton and hence is active, consuming energy . Upon entry to mitochondria, the pyruvate is decarboxylated, producing acetyl coA. Pyruvate decarboxylation is also known as the " pyruvate dehydrogenase reaction " because it also involves the oxidation of pyruvate.

. Suppose you start with 1 molecule of glucose and go through glycolysis to produce 2 molecules of pyruvate. These 2 molecules of pyruvate are then converted into acetyl CoA which then go through the TCA cycle. Approximately how many total ATP / ATP-equivalents can be formed through this process? (Account for NADH/FADH2 produced). Show where each molecule of ATP is generated from.
