Once electron carriers reach the ETC, however, a large amount of ATP is created through a process called oxidative phosphorylation. What are the main redox reactions in cellular respiration? They include glycolysis, the TCA Cycle, and oxidative phosphorylation. I. Glycolysis When food is eaten, ...
For fermentative organisms, however, ATP is generated through substrate-level phosphorylation and oxidation of electron donors coupled to the reduction of electron carriers like Nicotinamide adenine dinucleotide phosphate.* In this process (fermentation) ATP can also be generated through other processes such...
Electron-carriers (e.g. NADH and FADH2) shuttle the electrons down the electron transport chain. A series of redox reactions occur along the chain and culminates in the final electron acceptor, i.e. the molecular oxygen. More ATP is produced via a coupling mechanism through chemiosmosis in ...

Theelectron transportchain (ETC) is a series ofproteincomplexes located in the inner mitochondrialmembranethat facilitateoxidative phosphorylation. Activated carriers, NADH and FADH2, donate electrons, creating a proton gradient essential forATPsynthesis. Key complexes include NADH dehydrogenase,cytochromebc1,...
Electrons obtained from these sources are then transported through various electron carriers before protons are pumped through the membrane in order to produce a proton gradient. The gradient is then used by the enzyme ATP synthase to generate ATP. ...
This leaves an absence of electron (hole) in the impurity. These impurity atoms which are ready to accept bonded electrons are called “Acceptors“. With an increase in the number of impurities, holes (the positive charge carriers) are increased. Hence, it is called a p-type semiconductor. ...
Electrons move toward a positive terminal in an electric circuit. The electron flow, or moving charge, is therefore away from the negative terminal. The movement of electrons in a copper wire or other conductive material also generates a magnetic field that has a direction and magnitude ...
Example 3: In a classic nuclear physics experiment, an alpha particle was accelerated toward a gold nucleus. If the energy of the alpha particle was 5 MeV (Mega-electronvolts), how close to the gold nucleus could it come before being deflected? (An alpha particle has a charge of ...
Niacin (B3) Niacin represents an essential component of NAD and NADP, two electron carriers used in cellular respiration. Cellular respiration refers to the process of converting nutrients into energy. Dairy products and other foods high in protein tend to contain large amounts of niacin. Folate ...
