What else can I help you with?
Do reduced molecules have more energy than oxidized molecules?
No, oxidized molecules have more energy than reduced molecules.
Can a photon be oxidized by an electron from the valence shell of a molecule?
No, photons are elementary particles and do not participate in chemical reactions like oxidation. Oxidation involves the loss of electrons by a chemical species, not a photon. Photon interactions primarily involve electromagnetic forces.
How many molecules of oxygen are used during cell respiration?
During cell respiration, glucose is oxidized to produce energy. One molecule of glucose reacts with 6 molecules of oxygen to produce energy, water, and carbon dioxide.
Does the molecule that functions as a reducing agent in a oxidation-reduction reaction gain or lose electron?
A reducing agent loses electrons and is thereby oxidised.
When a reducing agent donates an electron to another molecule the reducing agent is?
oxidized. Reducing agents are substances that have a tendency to donate electrons, thus becoming oxidized themselves in the process.
In glycolysis for each molecule of glucose oxidized to pyruvate?
Two molecules of ATP are consumed in the energy investment phase, while four molecules of ATP and two molecules of NADH are produced in the energy payoff phase. This results in a net gain of two molecules of ATP per molecule of glucose oxidized to pyruvate.
If a molecule of ATP is oxidized becomes?
If a molecule of ATP is oxidized, it loses a phosphate group and is converted into ADP (adenosine diphosphate) along with release of energy that can be used by the cell for various processes.
Would a fully oxidized or fully reduced molecule be a better cellular energy source?
A fully reduced molecule would be a better cellular energy source because it has more energy stored in its chemical bonds compared to a fully oxidized molecule. Oxidation leads to the release of energy stored in chemical bonds, while reduction stores energy in those bonds.
What does a molecule that has been oxidized have?
Well it has less electrons than it had before. That is the definition of oxidation. The loss of electrons is oxidation. The gain of electrons is reduction.
When a glucose molecule loses a hydrogen atom as the result of an oxidation-reduction reaction the molecule becomes?
oxidized
When a molecule loses an electron the molecule has been?
When a molecule loses an electron the molecule has been ionized and oxidized.
Where a molecule gives up electrons and releases energy?
This process occurs during oxidation, where a molecule loses electrons and energy is released. Oxidation reactions are important in cellular respiration, where glucose is oxidized to release energy for the cell to use.
The molecule that functions as the reducing agent in a oxidation-reduction reaction?
The reactant that reduces another atom.
When a molecule of nad plus gains a hydrogen atom to become nadh does the molecule become phosphorylated or oxidized or reduced or redoxed?
When a molecule of NAD+ gains a hydrogen atom to become NADH, the molecule is reduced. Reduction is the gain of electrons by a molecule, which is what occurs in this process. This is part of a redox (reduction-oxidation) reaction where one molecule is reduced (NAD+) and the other molecule is oxidized (loses electrons).
When a molecule is reduced and when a molecule is oxidized?
A molecule is reduced when it gains electrons or hydrogen atoms, resulting in a decrease in its oxidation state. Conversely, a molecule is oxidized when it loses electrons or hydrogen atoms, leading to an increase in its oxidation state. This process often involves the transfer of electrons between molecules in redox reactions, where one molecule is oxidized and another is reduced simultaneously.
What loses energy?
Energy can be lost through various processes such as friction, heat transfer, sound emission, and radiation. When objects interact, energy can be transferred between them and some of it can be lost in these forms.
What component cellular respiration carries the energy from the reduced molecule to the oxidized molecule?
In cellular respiration, the component that carries energy from the reduced molecule (such as glucose) to the oxidized molecule (like oxygen) is the electron transport chain (ETC). The ETC consists of a series of protein complexes and electron carriers that transfer electrons derived from reduced coenzymes (NADH and FADH2) generated during earlier stages of respiration. As electrons move through the chain, their energy is used to pump protons across the mitochondrial membrane, creating a proton gradient that ultimately drives ATP synthesis.
