The oxidation of NADH during the conversion of pyruvic acid to carbon dioxide occurs in the citric acid cycle (Krebs cycle). The reaction can be simplified as follows:

[ \text{C}_3\text{H}_4\text{O}_3 , (\text{pyruvic acid}) + \text{NAD}^+ + \text{CoA} \rightarrow \text{C}_2\text{H}_3\text{O} + \text{CO}_2 + \text{NADH} + \text{H}^+ ]

In this process, pyruvic acid is decarboxylated to produce acetyl-CoA, releasing carbon dioxide and reducing NAD+ to NADH.

The breakdown of pyruvic acid occur?

Pyruvic acid breakdown occurs through a process called pyruvate oxidation, which takes place in the mitochondria. During this process, pyruvate is converted into acetyl-CoA, releasing carbon dioxide and producing NADH. Acetyl-CoA then enters the Krebs cycle to generate more ATP.

What is the equation for alcoholic fermentation after glycolysis?

The product of glycolysis is pyruvate. In alcoholic (ethanol) fermentation, pyruvate is converted into ethanol and carbon dioxide. The first step is decarboxylation, catalyzed by pyruvate decarboxylase: CH3COCOO- --> CH3CHO pyruvate --> acetaldehyde Then acetaldehyde is reduced to ethanol; this step is catalyzed by alcohol dehydrogenase and involves the oxidation of NADH+ + H+ to NADH: CH3CHO --> CH3CH2OH


What Krebs cycle step releases carbon dioxide?

When Pyruvic Acid is formed. The pyruvic acid molecules have one of their carbon atoms removed, in the form of CO2. The CO2 will then form coenzymes--> the enzymes that will form will continue on into the electron transport chain.

The Krebs cycle, it takes the pyruvic acid made in the first process glycolysis to make carbon dioxide and released electrons. It occurs inside the mitochondria matrix.

What would refer to the oxidation of glucose to pyruvic acid?

Well in respiration in mammals the first stage of respiration is called glycolysis which is the break down of glucose to pyruvic acid which makes a by-product of 36 ATP which go on to the second stage of carbon fixation. Not sure if thats what u mean hope I helped.
