Oxidation reactions through metabolism primarily result in the conversion of nutrients into energy, facilitating the production of adenosine triphosphate (ATP). These reactions also generate byproducts such as carbon dioxide and water, which are expelled from the body. Additionally, oxidation can lead to the formation of reactive oxygen species (ROS), which, if not regulated, may cause oxidative stress and damage to cells and tissues. Overall, these metabolic processes are essential for maintaining cellular functions and overall physiological health.
What else can I help you with?
Why does the oxidation reaction undergo reduction?
Chemical reactions that result in transference of electrons
What damages plant and animal tissue?
oxidation causes it, which happens as a result of photosynthesis for plants and metabolism for animals
Why phenol gets darkened on long standing?
Phenol gets darkened on long standing due to oxidation reactions that form quinones and polymers. These reactions are accelerated by exposure to light and air. The darkening of phenol is a result of the formation of colored compounds as a byproduct of these oxidation reactions.
Oxidation takes place at anode and reduction at cathode?
In an electrochemical cell, oxidation occurs at the anode, where electrons are lost as a result of a redox reaction. The anode is where oxidation half-reactions take place, generating electrons that flow through the external circuit to the cathode. Reduction, on the other hand, occurs at the cathode, where electrons are gained during the redox reaction. This flow of electrons from anode to cathode is what generates an electric current in the cell.
What substance accumulates in cell as a result anaerobic metabolism?
Lactic acid accumulates in cells as a result of anaerobic metabolism. This occurs when cells do not have enough oxygen to produce energy through aerobic respiration, and instead rely on anaerobic glycolysis to generate ATP.

Oxidation and reduction reactions are chemical processes that result in a gain or loss in?
Oxidation and reduction reactions are chemical processes that result in a gain or loss of electrons from reactant species. In oxidation, a species loses electrons, while in reduction, a species gains electrons. This transfer of electrons leads to changes in the oxidation states of the elements involved in the reaction.
Why phenol gets darkened on long standing?
Phenol gets darkened on long standing due to oxidation reactions that form quinones and polymers. These reactions are accelerated by exposure to light and air. The darkening of phenol is a result of the formation of colored compounds as a byproduct of these oxidation reactions.
How can oxidation numbers help chemists?
Oxidation numbers allow us to follow which species is being oxidised and which is being reduced. That way, we know which reactions are occurring and what the result will be.
What is the result of this oxidation?
Without knowing the specific compounds involved in the oxidation reaction, it is impossible to determine the exact result. Oxidation reactions typically involve the loss of electrons or an increase in oxidation state of an atom. The final product will depend on the reactants and conditions of the reaction.
What is an oxidation number and how does an atom get one?
Before involving any chemical reactions or bonds, an atom has an oxidation number of zero. Accepting electrons will lower the oxidation number to negative numbers. Discharging electrons such as metals will result in positive oxidation numbers.
Is oxidation endothermic?
An oxidation reaction is also known as a redox reaction. Not all redox reactions give off heat. Some redox reactions give off heat and some require heat from an outside source for the reaction to be completed.
What is adding oxygen to a substance called?
Adding oxygen to a substance is called oxidation. It can cause chemical reactions that result in changes to the substance's properties.
What identifies an oxidation-reduction reaction'?
An oxidation-reduction (redox) reaction involves the transfer of electrons between reactants. The substance that loses electrons is oxidized, while the substance that gains electrons is reduced. Redox reactions result in changes in oxidation states of atoms involved.
What type of reactions occur when a chemical substance loses electrons to another substance?
If one substance is losing electrons (where it is gaining charge, or oxidizing), we must assume those electrons are going to another substance in the reaction, which will cause the charge to go down, or reduce. This type of equation is called a Redox (reduction-oxidation) reaction.
How are bubbles produced in a voltaic cell?
Bubbles are produced in a voltaic cell through the electrolysis process that involves the generation of gas at the electrodes. At the anode, oxidation reactions can produce gas bubbles, while at the cathode, reduction reactions can also result in gas bubble formation. These bubbles are typically a byproduct of the electrochemical reactions occurring in the cell.
