Pyruvate Oxidation exam Flashcards

The second step of cellular respiration, occurring in the mitochondrial matrix, converting pyruvate into acetyl CoA, NADH, and CO2.

In the mitochondrial matrix.

2 acetyl CoA, 2 NADH, and 2 CO2 molecules.

It loses electrons, reducing NAD+ to NADH, and releases one carbon as CO2.

A molecule that carries electrons, produced during pyruvate oxidation by the reduction of NAD+.

3 carbon atoms.

A molecule formed from pyruvate during pyruvate oxidation, which enters the Krebs cycle.

CO2 (carbon dioxide).

The first stage of cellular respiration that produces 2 pyruvate molecules.

2 pyruvate molecules.

One carbon is released as CO2, and the remaining carbons form acetyl CoA.

The third step of cellular respiration where acetyl CoA is further processed for energy production.

2 NADH molecules.

It gains electrons lost by pyruvate, becoming NADH.

A multi-step process that converts glucose into energy, involving glycolysis, pyruvate oxidation, the Krebs cycle, and the electron transport chain.

2 CO2 molecules.

It enters the Krebs cycle for further energy production.

The location within the mitochondria where pyruvate oxidation occurs.

Pyruvate oxidation.

2 acetyl CoA molecules.

They are gained by NAD+, forming NADH.

Pyruvate.

Four stages: glycolysis, pyruvate oxidation, the Krebs cycle, and the electron transport chain.

To convert pyruvate into acetyl CoA, NADH, and CO2 for further energy production.

CO2 (carbon dioxide).

It enters the Krebs cycle.

2 pyruvate molecules.

Glycolysis produces pyruvate, which is then oxidized in the mitochondrial matrix during pyruvate oxidation.

It is the site where pyruvate oxidation and the Krebs cycle occur.
