What happens to the high-energy electrons held by NADH if there is no oxygen present?
What happens to the high energy electrons(and hydrogen)held by NADH if there is no O2 present?
In the absence of oxygen, the high-energy electrons carried by NADH cannot be transferred to the electron transport chain for oxidative phosphorylation. Instead, NADH donates its electrons to pyruvate, resulting in the production of lactate in animals (lactic acid fermentation) or ethanol and carbon dioxide in yeast (alcoholic fermentation). This process regenerates NAD+, allowing glycolysis to continue producing ATP anaerobically.
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atom as part of a water molecule?
8

What happens to the high-energy electrons held by NADH if there is no oxygen present?
What happens when hydrogen atom absorbs a quantum of enery?
The electrons move up to a higher energy level.
What happens to the high energy electrons and hydrogen held by NADH if there is no O2?
If there is no oxygen present, the high-energy electrons held by NADH cannot be passed along the electron transport chain for energy production, resulting in a buildup of NADH and disrupted cellular respiration. The fate of the high-energy electrons and hydrogen held by NADH may vary depending on the organism, but typically, fermentation pathways are activated to regenerate NAD+ so glycolysis can continue generating ATP anaerobically.
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of water molecule?
An oxygen atom has 6 electrons in its outermost energy level. When it shares electrons with two hydrogen atoms to form a water molecule, oxygen will share 2 of its electrons with each hydrogen atom, allowing each hydrogen to complete its outermost energy level with 2 electrons. This results in oxygen having a full outermost energy level with 8 electrons.
How many energy levels would electrons of hydrogen and helium fill?
Electrons of hydrogen fill up to two energy levels, while electrons of helium fill up to a total of two energy levels as well. Helium has an additional energy level compared to hydrogen because it has 2 electrons, filling up both the first and second energy level.
Which atom does not need 8 electrons in it outer energy level to be stable?
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
What happens to the energy of the electrons in the orbits as the radius of each orbit increases?
What happens to the energy of the electrons in the orbits of each orbit increases
How many electrons are in the second energy level of hydrogen?
Depends on the isotope can be 0 or 1 hydrogen is a highly unstable element that the electron Jumps betweent the two energy levels
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
What bacteria obtain energy by stripping hydrogen and electrons from ammonium ions?
Nitrosomonas is a bacteria that obtains energy by oxidizing ammonia and stripping hydrogen and electrons from ammonium ions in a process called nitrification.
What is the total number of electrons in the orbitals of each energy level of a HCl?
In a hydrogen chloride (HCl) molecule, there will be a total of 17 electrons. Hydrogen contributes 1 electron, while chlorine contributes 17 electrons. The electrons will be distributed among the different energy levels based on the electron configuration of hydrogen and chlorine atoms.
What happens to hydrogen when you burn wood?
When wood burns, the hydrogen present in the wood combines with oxygen in the air to form water vapor. This reaction releases heat energy and carbon dioxide as byproducts of combustion.
