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.

Which is true about how are cells use oxygen? A. When oxygen is present pyruvate is converted to lactate which enters the citric acid cycle. The reduced coenzymes donate hydrogen ions and high energy electrons to the electron transport chain, and oxygen acts as the final acceptor of hydrogen ions and low energy electrons after the hydrogen ions have passed through ATP synthase. B. When oxygen is present pyruvate is converted to Acetyl CoA which enters the citric acid cycle....
