Cellular respiration is a complex, multi-stage reaction. It starts with splitting apart a glucose molecule, a process called glycolysis. The next phase is called the Krebs cycle, the citric acid cycle or the tricarboxylic acid cycle (TCA cycle). The Krebs cycle is an aerobic process; that is, it needs oxygen to proceed.In Oxidization the electron density of an atom, or substance is drawn away from the substance being Oxidized.

Hybrid cars are becoming increasingly popular as more and more people are looking for ways to reduce their carbon footprint and save money on fuel costs. But what exactly is a hybrid car? In this article, we’ll explain the basics of hybrid ...The original meaning of oxidation was “adding oxygen,” so when oxygen is added to a molecule, the molecule is being oxidized. The reverse is true for reduction: if a molecule loses oxygen atoms, the molecule is being reduced. For example, the acetaldehyde (CH 3 CHO) molecule takes on an oxygen atom to become acetic acid (CH 3 COOH).Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD +, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy. Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA.reduction The loss of oxygen, gain of electrons, or gain of hydrogen by a substance during a chemical reaction. oxidise Chemical substances are oxidised by the addition of oxygen, removal of ...VIDEO ANSWER: What happens to a substance when it becomes oxidized?
