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.


The electron transport chain receives electrons directly from?

The electron transport chain receives electrons directly from NADH and FADH2, which are produced during the earlier stages of cellular respiration. These molecules donate their electrons to the complex proteins within the electron transport chain, allowing for the creation of a proton gradient that drives ATP production.


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.


What products of the citric acid cycle are needed for the electron transport chain?

NADH and FADH2 are the main products of the citric acid cycle that are needed for the electron transport chain. These molecules carry high-energy electrons to the electron transport chain, where they donate the electrons to generate ATP through oxidative phosphorylation.


The accompanying figure shows the electron transport chain what is the combination of substances that is initially added to the chain?

The combination of substances that is initially added to the electron transport chain is NADH and FADH2. These molecules carry electrons from previous steps in cellular respiration to the electron transport chain, where they donate their electrons to the chain to generate ATP.


Which molecule enter electron transport?

In the electron transport chain, the molecules that enter are NADH and FADH2. These molecules donate their electrons to the chain, which then pass along a series of protein complexes in the inner mitochondrial membrane to generate ATP through oxidative phosphorylation.


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.


Why do NADH and FADH2 donate electrons to different electron transport chain complexes?

NADH and FADH2 donate electrons to different complexes in the electron transport chain because they have different energy levels and transfer electrons at different points in the chain, allowing for efficient energy production through the generation of a proton gradient.


What are the 2 energy carriers that enter the electron transport chain and their energy can be transferred to ATP?

FAD and NADHThe pick up electrons, with attendant protons, to carry into the transport chain and become,FADH and NADH2


Starting molecule of electron transport chain?

The starting molecule of the electron transport chain is NADH or FADH2, which are generated during glycolysis and the citric acid cycle. These molecules donate high-energy electrons to the electron transport chain, which then pass through a series of protein complexes to generate ATP through oxidative phosphorylation.


Molecules that furnish electrons during a chemical reaction are called?

Molecules that furnish electrons during a chemical reaction are called reducing agents or electron donors. These molecules undergo oxidation as they donate electrons to another molecule, known as the oxidizing agent or electron acceptor.


The primary function of NADH and FADH2 is?

The primary function of NADH and FADH2 is to transfer electrons in cellular respiration. These molecules are key players in the electron transport chain, where they donate electrons to help generate ATP, the cell's energy currency.
