Well - this is a loaded question.
Think of the electron transport chain as a hydroelectric dam. Essentially different molecules love electrons more than others, by transferring the electron from somebody that is ok with having an electron to some who loves electrons, will result in a more stable system; but by stabilizing the system you release energy (remember that unstable processes need the input of energy), this released energy in terms of the electron transport chain is used to pump protons (H+ atoms) across a membrane, this is like taking water from the bottom of a hydroelectric dam and then putting it at the top again. This process of electrons being transferred from NADH (who is ok with having electrons) all the way through a number of proteins to oxygen (O2, who ADORES electrons) will release a lot of energy; at each step the energy is used to pump a H+ across the membrane (or pump water to the top of the damn); once the H+ are at the top of the dam, they can run through the turbine-like protein called ATP synthase and this downhill motion will allow it to synthesize ATP; a relatively unstable molecule (because of the 3 anionic Pi's!), due to its instability it will pop off Pi's and power processes!
So it's mostly all about using relative molecule's preference for electrons, using the happiness (energy released) for giving an electron to someone who loves it more to power the pumping of H+ across a membrane (like pumping water to the top of a dam) and then, with the current of H+ ATP synthase can make ATP to power bodily/cellular functions :)
YouTube the electron transport chain, there are a lot of tutorials on it.
What else can I help you with?
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.
The energy carrier NAD is reduced to what substance?
NAD is an energy carrier which is involved in the process of glycolysis. It is reduced to NADH when a hydrogen atom is added.
How do activated carriers facilitate the transfer of energy and molecules within biological systems?
Activated carriers facilitate the transfer of energy and molecules within biological systems by temporarily storing and transporting high-energy molecules, such as ATP or NADH, to where they are needed. These carriers can easily release their stored energy or molecules to drive essential biological processes, such as metabolism and cell signaling.
Energy is transferred from nadh and fadh2 to atp during?
Energy is transferred from NADH and FADH2 to ATP during cellular respiration in the mitochondria. The electron transport chain uses the energy from these molecules to pump protons across the inner mitochondrial membrane, creating a proton gradient. This gradient drives the production of ATP through the process of oxidative phosphorylation.
When NAD reacts with hydrogen and gains two electrons NAD?
is reduced to NADH. This reaction is an important step in the process of cellular respiration, where NADH then carries the electrons to the electron transport chain to produce ATP energy.
What is electron carrier use to transfer energy in cellular respiration?
NADH.
Is NADH an energy storage compound used in respiration?
Yes, NADH is an energy carrier molecule that is used in cellular respiration to transfer high-energy electrons from glucose to the electron transport chain. This results in the production of ATP, the cell's main energy source.
Which molecule, NAD or NADH, possesses more energy?
NADH possesses more energy than NAD.
Which molecule, NADH or NAD, possesses more energy?
NADH possesses more energy than NAD.
Does NAD possess more energy than NADH?
Yes, NAD possesses more energy than NADH.
What does nadh mean in science?
NADH (nicotinamide adenine dinucleotide) is a coenzyme found in cells that plays a crucial role in the process of cellular respiration. It serves as an electron carrier, helping to transfer electrons from one molecule to another during the production of ATP, the cell's main energy source. NADH is produced during the breakdown of sugars and fats in the cell.
Which molecule, NAD or NADH, possesses higher potential energy?
NADH possesses higher potential energy compared to NAD.
Does NAD have more energy than NADH?
NADH has more energy than NAD. NADH contains high-energy electrons that can be used in cellular respiration to produce ATP, which is the cell's main energy currency. NAD serves as an electron carrier in various metabolic reactions.
Nad plus picks up electrons and hydrogen forming?
NAD+ picks up two electrons and one hydrogen atom, forming NADH. This reduction reaction allows for the transfer of energy in biochemical processes such as cellular respiration.
What energy-carrierz molecules are produced by glycolysis?
Nadh and 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 differences between NADH and NAD in terms of their roles in cellular metabolism?
NADH is a reduced form of NAD, meaning it has gained electrons and is used in energy production during cellular respiration. NAD, on the other hand, acts as a coenzyme in various metabolic reactions, accepting and donating electrons to facilitate energy transfer.
