NADH is produced during?
NADH is produced during glycolysis, the citric acid cycle, and the electron transport chain in cellular respiration. It is a reducing agent that carries high-energy electrons to the electron transport chain to produce ATP.
Which molecule are high-energy electrons from glycolysis and the Krebs cycle ultimately transferred to?
High-energy electrons from glycolysis and the Krebs cycle are ultimately transferred to oxygen molecules during oxidative phosphorylation in the electron transport chain to produce ATP.
What happens when NAD plus becomes NADH?
When NAD+ is reduced to NADH, it accepts two electrons and a hydrogen ion, becoming a carrier of high-energy electrons. This conversion usually occurs during cellular respiration where NADH is a key player in transferring electrons to the electron transport chain for ATP production.
During glycolosis when glucose is catabolized to pyruvate most of the energy of glucose is?
During glycolysis, most of the energy of glucose is conserved in the form of ATP and NADH. These high-energy molecules are produced through a series of enzymatic reactions that break down glucose into pyruvate. The ATP and NADH provide energy for cellular processes and are crucial for metabolism.
How does fermentation enable glycosis to continue producing ATP?
During fermentation, cells convert NADH to NAD+ by passing high-energy electrons back to pyruvic acid. This action converts NADH back into the electron carrier NAD+, allowing glycolysis to continue producing a steady supply of ATP.
What is the carrier for energy and high energy electrons during glycolysis?
nadh!
Are there other high energy products of glycolysis?
pyruvate, atp, nadh
What is the difference between NAD and NADH?
NAD (nicotinamide adenine dinucleotide) is a coenzyme that can accept or donate electrons during cellular respiration. NADH is the reduced form of NAD, meaning it has gained electrons. NADH is a high-energy molecule that carries electrons to the electron transport chain for ATP production.
What goes in and comes out of glycolysis?
In glycolysis, glucose (a 6-carbon sugar molecule) goes in and is converted into two molecules of pyruvate (a 3-carbon compound). This process also produces ATP (energy) and NADH (a molecule that carries high-energy electrons).
NADH is produced during?
NADH is produced during glycolysis, the citric acid cycle, and the electron transport chain in cellular respiration. It is a reducing agent that carries high-energy electrons to the electron transport chain to produce ATP.
What molecule stores the high energy electrons removed from glucose in glycolysis?
In glycolysis, the high-energy electrons removed from glucose are stored in the molecule NADH. During the process, two molecules of NAD+ are reduced to NADH as glucose is broken down into pyruvate. This conversion allows the energy extracted from glucose to be captured and utilized in subsequent cellular respiration processes.
Which molecule are high-energy electrons from glycolysis and the Krebs cycle ultimately transferred to?
High-energy electrons from glycolysis and the Krebs cycle are ultimately transferred to oxygen molecules during oxidative phosphorylation in the electron transport chain to produce ATP.
What produces ATP nadh and co2?
The process of cellular respiration in mitochondria produces ATP, NADH, and CO2. During glycolysis and the citric acid cycle, glucose is broken down to produce NADH and carbon dioxide. The electrons carried by NADH are used in the electron transport chain to generate ATP through oxidative phosphorylation.
What would happens to high energy electrons and hydrogen held by NADH if there is no O2 present?
Without oxygen present, high-energy electrons from NADH cannot be passed down the electron transport chain for ATP production through oxidative phosphorylation. This can lead to a buildup of NADH and a decrease in the availability of NAD+ for glycolysis and the Krebs cycle. As a result, the cell may shift to less efficient processes like fermentation to regenerate NAD+ and keep glycolysis running.
How is glycolysis turned off?
When an enzyme in a pathway is inhibited by the product of the reaction sequence, feedback inhibition occurs. The product molecule "feeds back" to stop the reaction sequence when the product is abundant.
What happens to the high energy electrons and hydrogen held by NADH if there is no O2?
If there is no oxygen present, the high-energy electrons held by NADH cannot be passed along the electron transport chain for energy production, resulting in a buildup of NADH and disrupted cellular respiration. The fate of the high-energy electrons and hydrogen held by NADH may vary depending on the organism, but typically, fermentation pathways are activated to regenerate NAD+ so glycolysis can continue generating ATP anaerobically.
What happens when NAD plus becomes NADH?
When NAD+ is reduced to NADH, it accepts two electrons and a hydrogen ion, becoming a carrier of high-energy electrons. This conversion usually occurs during cellular respiration where NADH is a key player in transferring electrons to the electron transport chain for ATP production.
