What is the oxidizing agent in pyruvate oxidation?
o In glycolysis, glucose is oxidized to two pyruvate molecules with NAD+ as the oxidizing agent. o Glycolysis is exergonic and produces 2 ATP (net) by substrate-level phosphorylation. If oxygen is present, additional ATP can be generated when NADH delivers its electrons to the electron transport chain.
What is the oxidizing agent in pyruvate to lactate?
The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD+. Electrons from NADH and a proton are used to reduce pyruvate into lactate.
Is pyruvate an oxidizing agent?
Pyruvate (oxidizing agent is being reduced (gains electrons) and since NADH is being oxidized, pyruvate is the one being reduced)
Which is the oxidizing agent in the following reaction?
The species gaining electrons is called the oxidizing agent or oxidant. It is reduced. In this given reaction the oxidising agent is oxygen because it oxidises methane to carbon dioxide and oxygen is reduced to water.
Is lactate an oxidizing agent?
As a reducing agent, lactic acid is readily oxidized. Particularly with nitric acid, lactic acid acts autocatalytically and exothermically after a brief induction period, followed by vigorous gas evolution after several hours. As an acid, lactic acid reacts readily with bases.
Which of the following is the oxidizing agent in this reaction pyruvate NADH → lactate NAD+?

| When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs? | The pH of the matrix increases |
Is NADH an oxidizing agent?
Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. The cofactor is, therefore, found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. This reaction forms NADH, which can then be used as a reducing agent to donate electrons.
What is the oxidizing agent in the following reaction pyruvate NADH H lactate NAD+?

What is the oxidizing agent in the following reaction pyruvate NADH H?
Which is the oxidizing agent?
Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction.
How is pyruvate an oxidizing agent?
Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.
Is NADH the oxidized form of NAD+?
Generally, NAD exists in two forms such as reduced and oxidized forms. The reduced form of NAD is designated as NADH and oxidized form as NAD+. Each form helps to carry electrons from one reaction to another. It also plays a vital role in energy production via redox reactions.
