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.
When is the electron transport chain carried out?
Plants, fungi, and animals are all eukaryotes and possess mitochondria, which is the site of the electron transport chain. Prokaryotes have no mitochondria and perform the electron transport chain across their cell membranes. Electron transport chain also occurs in thylakoid membrane of chloroplasts.
Where is energy stored in NADH andFADH?
In NADH and FADH2, energy is stored in the high-energy electrons that are carried by these molecules. During cellular respiration, these electrons are transferred to the electron transport chain, where their energy is used to create a proton gradient that drives ATP synthesis.
What two electron carrier molecules feed electrons into the electron transport chain?
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 rule is violated by the following electron configuration 1s2 2s2 2p6 3s6 3p6?
The electron configuration violates the aufbau principle, which states that electrons fill orbitals from lowest to highest energy levels. In this case, the 3s orbital should only have 2 electrons maximum before moving to the 3p orbital.
The electrons from glucose are carried to the electron transport system by which of the following?
NAD+
What an electron transport chain?
in this step the energy carried by electrons is used to synthesize (ATP). In electron transport chain NADH and FADH2 realese electrons and hydrogen ions. These electrons are taken up by a series of electron carriers. When electrons move through the series of electron carriers they lose electrons and hydrogen ions combine with moleculaer oxygen to form water.
What is the function of oxygen in aerobic repsiration?
Oxygen serves as an electron acceptor. When food is completely metabolised in the organism, it is decomposed to electrons, protons and CO2. The electrons are carried by NADH to mitochondria, to electron-transport chain. At the end of the electron transport chain, oxygen receives electrons, thus providing for maximal yield of energy carried by those electrons (in the electron-transport chain, they are used for pumping protons across the mitochondrial membrane, thus proton gradient which empowers ATPase, is maintained). At last, the ATPase enzyme produces ATP, the usable form of energy.
What electron carried the current in a metal conductor?
The valance electrons.
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.
Where do electrons from the Krebs cycle go next?
Electron Transport The point of the kreb's cycle is to create energy. The energy made is in the form of ATP (Adenosinetriphosphate) which the body uses immediatley or is in the form of electrons carried by NADH or FADH2. These then go on to the electron transport chain where more molecules of ATP are created.
Which reaction of the Krebs cycle is carried out at the electron transport chain?
Succinate to fumarate
When is the electron transport chain carried out?
Plants, fungi, and animals are all eukaryotes and possess mitochondria, which is the site of the electron transport chain. Prokaryotes have no mitochondria and perform the electron transport chain across their cell membranes. Electron transport chain also occurs in thylakoid membrane of chloroplasts.
What is the origin of the H plus and electrons that are transferred to NAD plus?
The origin of H+ and electrons transferred to NAD+ during cellular respiration is from the breakdown of glucose in the process of glycolysis and the citric acid cycle. These processes generate high-energy electrons that are carried by electron carriers like NADH to the electron transport chain, where they are used to create a proton gradient for ATP production.
Where do the final steps in aerobic cellular respiration occur?
The final steps of aerobic cellular respiration occur in the mitochondria, specifically in the electron transport chain and oxidative phosphorylation. Here, most of the ATP is produced through the electron transport chain by using the energy carried by electrons from previous stages of respiration.
What step during Krebs cycle do electrons pass down the electron transport chain?
During the Krebs cycle, the electrons are carried by NADH and FADH2 to the electron transport chain, where they pass down a series of protein complexes to generate ATP through oxidative phosphorylation. This occurs after the formation of NADH and FADH2 during the Krebs cycle.
Where is energy stored in NADH andFADH?
In NADH and FADH2, energy is stored in the high-energy electrons that are carried by these molecules. During cellular respiration, these electrons are transferred to the electron transport chain, where their energy is used to create a proton gradient that drives ATP synthesis.
