Most of the NADH that delivers high-energy electrons to the electron transport chain comes from?
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from the citric acid cycle (Krebs cycle) during cellular respiration. This cycle generates NADH as a byproduct when converting acetyl-CoA to CO2, which is then used to produce ATP in the electron transport chain.
Where does the energy to make ATP from ADP come from?
photosinthesis During the light reactions of photosynthesis, water is split to create free protons (hydrogen minus an electron) within the thylakoid. The increasing number of protons also transported across the thylakoid membrane by an electron transport system, establish a concentration gradient where many hydrogen are present inside the thylakoid, as compared to the number outside. The diffusion (chemiosmosis) of these protons through the enzyme ATP synthase provides the energy needed to allow for the condensation reaction which fixes the third phosphate group onto the ADP molecule.
In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.
What is Fe?
Fe is the chemical symbol for iron, a metallic element found in abundance in the Earth's crust. It is an essential nutrient for many organisms and plays a crucial role in various biological processes, including oxygen transport in the blood. Iron is also used in industry for the production of steel and other materials.
In beta Decay a neutron is converted into a proton and what?
In beta decay, the nucleus of the atom emits an electron. This is a new electron, not one of the electrons in the electron cloud. This does indeed have the effect of changing a neutron into a proton, because total charge has to be conserved - if a new negative thing exists, there has to be a new positive thing too. But the mass has to stay the same too - conveniently, protons and neutrons have almost the same mass.
What is the final hydrogen acceptor in electron transport and where did it come from?
The final hydrogen acceptor in the electron transport chain is Oxygen. It comes from the ionization of water. Hope this helps. The final hydrogen acceptor in the electron transport chain is Oxygen. It comes from the ionization of water. Hope this helps.
What is a waste product of the electron transport chain?
Protons fall down their concentration gradient through the ATP-synthase and are picked up by oxygen, along with electrons, to make water. So, ATP and water " comes out " the electron transport chain.
What molecule is the final electron acceptor at the end of the cellular respiration transport chain?
The final electron acceptor at the end of the cellular respiration electron transport chain is oxygen. Oxygen accepts electrons and protons to form water during the process of oxidative phosphorylation.
Where does oxygen come from in oxidative phosphorylation?
Oxygen in oxidative phosphorylation comes from the air we breathe. During the electron transport chain, oxygen acts as the final electron acceptor, combining with protons to form water. This reaction is essential for the generation of ATP, the energy currency of the cell.
What is the incoming energy source for electron transport chain?
The electron transport chain is the driving energy behind ATP synthesis. The energy itself comes from electron donors. In chloroplast, this donor's glucose.
IS hydrogen necessary in the electron transport chain comes from the splitting of carbon dioxide molecules?
Hydrogen is essential in the electron transport chain, but it does not come from the splitting of carbon dioxide molecules. Instead, hydrogen is derived from the splitting of water molecules during the light reactions of photosynthesis. This hydrogen is then used to generate a proton gradient that drives ATP synthesis in the electron transport chain.
Is the energy produced from respiration coming from the Krebs cycle or electron transport?
Most of the energy comes from the electron transport chain by oxidative phosphorylation. However there is energy produced in the Krebs cycle and Glycolysis this is called substrate level phosphorylation.
Is nitrogen required in the stage of respiration?
Yes, oxygen is the fuel for respiration... oxygen + glucose = carbod dioxide + water + Energy However, the carbon dioxide and oxygen for a plant or tree would be the other way round because plants breath in co2 and give out oxygen.
Where does the oxygen in ETC come from?
The oxygen in the electron transport chain (ETC) comes from the air we breathe. When we inhale, oxygen is taken up by our lungs and transported in the blood to cells where it is used in the mitochondria for energy production through cellular respiration.
Is oxygen used in the TCA cycle?
No, oxygen is not directly used in the TCA (tricarboxylic acid) cycle. The TCA cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria and is primarily involved in generating energy from carbohydrates, fats, and proteins. Oxygen is used in the electron transport chain, which is a separate process that follows the TCA cycle and is responsible for the final stages of cellular respiration.
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from?
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from the citric acid cycle (Krebs cycle) during cellular respiration. This cycle generates NADH as a byproduct when converting acetyl-CoA to CO2, which is then used to produce ATP in the electron transport chain.
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.
