As we sit here reading and writing, our brain cells are hard at work trying to understand the world around us. They receive information from our bodies, process it in a series of signals and then send more information back to the body. Millions of cells are involved in this process, which goes on in the blink of an eye. NADH is a crucial coenzyme in making ATP. It exists in two forms in the cell: NAD+ and NADH. The first form, NAD+, is called the oxidized form. When a molecule is in an oxidized state, it means it can accept electrons, tiny negatively charged particles, from another molecule. After it gets the electrons, it has a negative charge, so it also picks up a hydrogen atom from the surrounding environment, since hydrogen atoms are positively charged. Now, we have the reduced form, or NADH. The two pyruvate are converted to another molecule called acetyl-CoA where they enter the mitochondria for the citric acid cycle. During the citric acid cycle, six electrons are harvested as NADH, and acetyl-CoA is regenerated, hence the 'cycle' part of the citric acid cycle. FADH2 is also made. FADH2 carries an extra electron, allowing it to make more energy per molecule t...

NAD+ and NADH are two forms of a coenzyme called nicotinamide adenine dinucleotide (NAD). NAD is a coenzyme, which means that it works with enzymes to facilitate chemical reactions in the body. NAD plays a crucial role in many important biological processes, including the metabolism of carbohydrates, fats, and proteins, as well as DNA repair and signaling. Table of Contents • • • • • • • NAD is found in a variety of foods, including meat, fish, and dairy products, and can also be synthesized by the body from the amino acid tryptophan. NAD deficiency can lead to several health problems, including fatigue, muscle weakness, rashes, and impaired immune function. 1 The Biochemistry This file by NADH is important for synthesizing adenosine triphosphate (ATP), the energy currency of the cell. Through the process of oxidative phosphorylation, NADH donates its hydrogen atoms and electrons to the electron transport chain, where they are used to produce ATP. There is a tight coupling between breaking down fats and glucose to reduce NAD+ to become NADH and then NADH reducing the first complex in the electron transport chain to produce ATP. NAD+ and NADH are constantly being interconverted in the cell, with NAD+ converted to NADH using energy from glucose metabolism and NADH converted back to NAD+ through the process of cellular respiration. Hydrogen ions move across the mitochondrial membrane, and oxygen accepts the electrons at the end of the electron transport chain. This balance is...

Cellular respiration is the process of utilizing oxygen and food molecules to create energy, carbon dioxide, water, and waste products. Basically, respiration is how we convert food into energy using water and oxygen. Respiration consists of three separate metabolic phases: glycolysis, the Krebs cycle, and the electron transport chain. We will not be going into any great detail on these three phases here. Instead, we'll be focusing on two compounds, FADH2 and NADH, and how they are incorporated into respiration. Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain. Nicotinamide adenine dinucleotide, or NADH, is a similar compound used more actively in the electron transport chain as well. In fact, more NADH is produced and used than FADH2 in the process of creating energy. There are actually six NADH produced and only two FADH2 molecules. FADH2 and NADH are created from FAD and NAD+ through reduction-oxidation reactions in the Krebs cycle during respiration as seen below: This cycle gives off small amounts of energy in the form of adenosine triphosphate, or ATP, and produces these compounds, FADH2 and NADH. The Krebs cycle is like a wheel. Every time it makes one full rotation, energy is created and released. As you can see from the diagram, the NAD+ and FAD are brought in at key points throughout the cycle and are attached to other electrons resultin...

At the core of the trillions of cells that make up the human body, each choreographing countless processes, sits NADH is very similar to NAD+, the only difference is a hydride. What’s a hydride? A hydride is a hydrogen atom with an extra electron. That is, a neutrally charged hydrogen atom holding on to a negatively charged electron. This gives hydride an overall negative charge: H + e- = H- Here, the hydrogen atom is denoted by an H, the electron by an e-, and the hydride by an H-. Since NAD+ is positively charged, adding a hydride to an NAD+ molecule results in a neutrally charged NADH molecule: NAD+ + H- = NADH To summarize, the difference between NAD+ and NADH is a hydride. NADH is bound to a hydride and NAD+ is not. Importantly, the hydride contains electrons and this is why NAD+ is considered an electron carrier. NAD+ the Electron Carrier NAD+ is an electron carrier because it carries the electrons of a hydride from one region of a cell to another. The structure of NAD+ provides a stable shuttle for the movement of electrons across the reactive landscape that is the internal environment of a cell. Without molecules like NAD+, electrons could hardly make it to their proper destination. This process of moving electrons around makes NAD+ and NADH oxidation-reduction, or “redox” molecules. Oxidation and Reduction Oxidation and reduction are terms to describe when molecules gain or lose electrons. Reduction is when a molecule gains electrons, such as when NAD+ gains the e...

Citric acid cycle. The acetyl CoA combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule. ATP (or, in some cases, GTP), NADH, and FADH_2 are made, and carbon dioxide is released. These reactions take place in the mitochondrial matrix. • Oxidative phosphorylation. The NADH and FADH_2 produced in other steps deposit their electrons in the electron transport chain in the inner mitochondrial membrane. As electrons move down the chain, energy is released and used to pump protons out of the matrix and into the intermembrane space, forming a gradient. The protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion. These electrons come originally from glucose and are shuttled to the electron transport chain by electron carriers NAD + \text_2 FADH 2 ​ start text, F, A, D, H, end text, start subscript, 2, end subscript .
