What happens to high energy electrons (and hydrogen)held by NADH if there is no O2 present?
In the absence of oxygen, high-energy electrons held by NADH are transferred to pyruvate during the process of fermentation. This transfer regenerates NAD+, allowing glycolysis to continue and produce ATP, albeit in much smaller amounts compared to aerobic respiration. In alcoholic fermentation, pyruvate is converted into ethanol and carbon dioxide, while in lactic acid fermentation, it is converted into lactic acid. This process allows cells to maintain energy production under anaerobic conditions.

How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
What is the maximum number of electrons that can be present in an atom having three principal energy levels?
The maximum number of electrons that can be present in an atom with three principal energy levels is 18. This is because the first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons.
What happens to the electrons when sunlight hits the leaves?
When sunlight hits the leaves, the energy from the light is absorbed by chlorophyll, the green pigment in the chloroplasts. This absorbed energy excites electrons in the chlorophyll molecules, raising them to a higher energy state. These high-energy electrons are then transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis, which ultimately converts light energy into chemical energy stored in glucose.

How many total electrons can be present in the third principle energy level?
18 electrons.
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
What happens when an atom has more electrons than can fit in one energy?
Answer this question… The extra electrons begin to fill the next energy level.
When chlorophyll absorbs light energy what happens to its electrons?
It becomes excited.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
What happens to the electrons after absorbing energy from light?
After absorbing energy from light, electrons in an atom can move to higher energy levels or be released from the atom altogether in a process called photoemission.
Valence electrons are present in more than one what?
Valence electrons are present in more than one energy level or shell around an atom's nucleus. They are the electrons involved in chemical bonding and determining the reactivity of an element.
What happens after proton pumps in mitochondria have depleted electrons of their energy during ATP production?
After the protons pumps in the mitochondria that have depleted the electrons of the energy the ATP production will reduce.
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
What happens a flame test?
Electrons are excited to higher energy levels and their emissions are observed.
