What two electron carrier molecules feed electrons into the electron transport chain?
NADH and FADH give high energy e- to the ETC which produces a high concentration gradient of hydrogen ions which then feed down into ATP synthase. The energy of the hydrogen ions moving down the ATP synthase generates the production of 36ATP in the mitochondria cristae.
The two electron carrier molecules that feed electrons into the electron transport chain are NADH and FADH2. These molecules are produced during glycolysis and the citric acid cycle, respectively. The electrons carried by NADH and FADH2 are then transferred to the electron transport chain to generate ATP through oxidative phosphorylation.

What are the two energy carrier molecules used to transfer energy from the citric acid cycle to the electron transport chain?
The two energy carrier molecules used are NADH and FADH2. These molecules are produced during the citric acid cycle and deliver electrons to the electron transport chain, where they drive the production of ATP through oxidative phosphorylation.
What compound is NADH converted to when it transfers high energy electrons to the first electron carrier?
NADH is converted to NAD+ when it transfers high-energy electrons to the first electron carrier of the electron transport chain.
What electron move high energy between photosystems?
The electrons that move between photosystems in photosynthesis are energized by sunlight and carried by electron carrier molecules such as plastocyanin and ferredoxin. These high-energy electrons are transferred through a series of redox reactions in the electron transport chain to generate ATP and NADPH for the light-dependent reactions of photosynthesis.
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 is the Oxidized form of the most common electron carrier needed in both glycolysis and Krebs cycle?
The oxidized form of the most common electron carrier needed in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons during the oxidation of substrates and is converted to its reduced form, NADH, which then delivers the electrons to the electron transport chain for ATP production.
What are the electron carrier molecules of aerobic respiration?
The electron carrier molecules of aerobic respiration are NADH and FADH2. These molecules transport electrons from the citric acid cycle and glycolysis to the electron transport chain in the mitochondria, where ATP is produced through oxidative phosphorylation.
What allows the passage of electrons along the series of carrier molecules from higher to a lower energy level?
The electron transport chain.
What compound is the source of electrons for linear electron flow?
In linear electron flow in the light reactions of photosynthesis, water is the source of electrons. The process involves the splitting of water molecules to release electrons, which are then used to reduce the electron carrier molecules in the electron transport chain.
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
Why do high-energy electrons need carrier molecules?
High-energy electrons are unstable and reactive, so they need carrier molecules to transport them safely without causing damage to the cell. Carrier molecules such as NADH and FADH2 can carry high-energy electrons during cellular respiration, allowing them to participate in energy-producing reactions without causing harm.
What are the two energy carrier molecules used to transfer energy from the citric acid cycle to the electron transport chain?
The two energy carrier molecules used are NADH and FADH2. These molecules are produced during the citric acid cycle and deliver electrons to the electron transport chain, where they drive the production of ATP through oxidative phosphorylation.
What are the types of carrier molecules for the ETC and where are they found?
The carrier molecules for the electron transport chain (ETC) are flavoproteins, iron-sulfur proteins, coenzyme Q, and cytochromes. These molecules are found embedded in the inner mitochondrial membrane where they shuttle electrons during the process of oxidative phosphorylation.
What is passage of electrons along a series of carrier molecules from a higher to a lower energy level?
This is known as the electron transport chain, which occurs during cellular respiration and photosynthesis. Electrons move along a series of carrier molecules embedded in the inner mitochondrial membrane or thylakoid membrane, releasing energy that is used to generate ATP or NADPH, respectively. The flow of electrons helps create a proton gradient that drives ATP synthesis.
What compound is NADH converted to when it transfers high energy electrons to the first electron carrier?
NADH is converted to NAD+ when it transfers high-energy electrons to the first electron carrier of the electron transport chain.
Why is the cristae the only possible place for the electron transport molecule in the mitochodria?
Because the electron carrier molecules, such as the cytochromes, are located in the cristae.
In the electron transport chain what keeps the electrons moving along from the first to the last chemical carrier?
NITROGEN
What are the electrons associated with the hydrogen atom in glucose during aerobic respiration?
The electrons associated with the hydrogen atom in glucose during aerobic respiration are transferred to the electron carrier molecules NAD+ and FAD. These carriers transport the electrons to the electron transport chain in the mitochondria, where they ultimately combine with oxygen to form water. This process generates ATP, the energy currency of the cell.
