Does one molecule of glucose have more energy than two molecules of pyruvate?

One molecule of glucose contains more energy than two molecules of pyruvic acid.

Why does lactic acid have more energy than pyruvic acid?

Pyruvic acid is reduced by NADH forming a molecule of lactic acid. The process is energetically wasteful because so much free energy remains in the lactic acid molecule.

Which two molecules provide the most ATP?

The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

What happens to the 2 pyruvate molecules?

Enzymes split a molecule of glucose into two molecules of pyruvate. This releases energy, which is transferred to ATP. During this stage, high-energy electrons are also transferred to molecules of NADH.

Does pyruvate have more or less potential energy than glucose?

Pyruvate is at a lower point than glucose in Model 1, and four ATP molecules are made as PGAL is converted to pyruvate, so pyruvate has less potential energy than glucose.

Does one molecule of ATP contains more energy than one molecule of glucose?

Let’s take a closer look at a molecule of ATP. Although it carries less energy than glucose, its structure is more complex. The “A” in ATP refers to the majority of the molecule, adenosine, a combination of a nitrogenous base and a five-carbon sugar.

Why does pyruvic acid have less energy than glucose?

Are pyruvate and pyruvic acid the same?

pyruvic acid, (CH3COCOOH), is an organic acid that probably occurs in all living cells. It ionizes to give a hydrogen ion and an anion, termed pyruvate. Biochemists use the terms pyruvate and pyruvic acid almost interchangeably.

What generates the most ATP?

The electron transport chain
Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.

Which process generates the greatest amount of energy?

aerobic respiration
The process of aerobic respiration produces a massive amount of energy. This process tends to produce approximately 38 ATP molecules.

Why is pyruvate converted to acetyl CoA?

After glycolysis, pyruvate is converted into acetyl CoA in order to enter the citric acid cycle.

How does pyruvate molecules produced during the glycolysis stage?

The word glycolysis means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid). In glycolysis, glucose (C6) is split into two 3-carbon (C3) pyruvate molecules. This releases energy, which is transferred to ATP.
