How does the electron transport chain use the high energy electrons from glycolysis and the Krebs cycle?
It passses them down a chain of proteins. These proteins use the energy in the electrons to create concentration gradients, which build up on one side of the membrane. Im pretty such off the top of my head that this concentration is of H+ atoms inside the inner membrane of the mitochondria, but im not positive. Anyways, once this concentration is great enough, the particles go through what is known as chemiosmosis, in which they go through a protein in the membrane called ATP synthase, which acts a kind of pump. this pump is powered by this concentration gradient, and as H+ ions go out of the membrane through this pump, they give the energy needed to phosphorylate ADP into ATP, making energy.
What else can I help you with?
What do glycolysis and the electron transport chain have in common?
The reduced form of the energy carrying molecules like NADH,FADH2 released from glycolysis send to electron transport system where these energy molecules are further acted by dehydrogenase to remove electrons and ATP is generated.
Most energy that enters electron transport enters as?
Most energy that enters the electron transport chain comes from the oxidation of glucose during glycolysis and the citric acid cycle. This energy is then transferred to the electron carriers NADH and FADH2, which deliver the electrons to the electron transport chain to generate ATP through oxidative phosphorylation.
What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
Where does glycolysis and Krebs cycle and electron transport chain occur?
Glycolysis occurs in the cytoplasm of the cell, where glucose is broken down into pyruvate. The Krebs cycle (or citric acid cycle) takes place in the mitochondria, specifically in the mitochondrial matrix, where pyruvate is further oxidized to produce energy carriers. The electron transport chain is located in the inner mitochondrial membrane, where the energy from electrons is used to produce ATP through oxidative phosphorylation.
What happens to the energy carrying electrons during glycolysis?
During glycolysis, energy-carrying electrons are transferred from glucose to electron carrier molecules, primarily NAD+ (nicotinamide adenine dinucleotide), which is reduced to NADH. This process occurs as glucose is broken down into pyruvate, generating a small amount of ATP in the process. The NADH produced can later be used in the electron transport chain to generate additional ATP under aerobic conditions. Thus, glycolysis not only facilitates energy release but also sets the stage for further energy extraction in cellular respiration.
What do glycolysis and the electron transport chain have in common?

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.

Most energy that enters the electron transport chain comes from the oxidation of glucose during glycolysis and the citric acid cycle. This energy is then transferred to the electron carriers NADH and FADH2, which deliver the electrons to the electron transport chain to generate ATP through oxidative phosphorylation.
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.
Where does the electron transport chain get the high-energy electrons that are passed down the chain?
The high-energy electrons in the electron transport chain are derived from molecules like NADH and FADH2, which are generated during cellular respiration in processes like glycolysis and the citric acid cycle. These molecules donate their electrons to the chain, where they are passed down through a series of protein complexes to generate ATP.
What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
3 main events of cellular respiration?
Glycolysis breaks down glucose into pyruvate, producing a small amount of ATP. The Krebs cycle further breaks down pyruvate to generate more ATP and high-energy electrons. The electron transport chain uses these high-energy electrons to generate a large amount of ATP through oxidative phosphorylation.
During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?
NADH and FADH2 donate electrons to the electron transport chain at the lowest energy level during aerobic respiration. These molecules are produced during earlier stages of cellular respiration (glycolysis and the citric acid cycle) and deliver high-energy electrons to the electron transport chain for ATP production.
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 does the electron transport chain use the high energy electrons for the Krebs cycle for?
The electrons are passed down the electron transport chain for use in ATP production.
What is the energy of the high energy electrons used for every time high energy electrons move down the electron transport chain?
To transport H+ ions out of the matrix.
What is the intermediate electron acceptor for oxidations that occur in both glycolysis and in Krebs cycle reactions?
The intermediate electron acceptor for oxidations in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons and becomes reduced to NADH during these metabolic pathways. NADH can then donate its electrons to the electron transport chain for further energy production.
