This is a simplified diagram that is designed to help us get a feel for how oxidative phosphorylation works. In a real mitochondrion, the matrix would be much a much larger …

Substrate level phosphorylation (physical addition of phosphate to the ADP and building ATP) can happen during glycolysis and TCA in the matrix of mitochondria.

In this article, we'll examine oxidative phosphorylation in depth, seeing how it provides most of the ready chemical energy (ATP) used by the cells in your body.

When a cell is producing lactic acid, does it then rely on oxidative phosphorylation or substrate-level phosphorylation for ATP generation?

We might start off by just getting ourselves organized and reminding ourselves that there are two kind of main ways that we produce ATP in cellular respiration so, the first minor contribution …

This example shows how reaction coupling involving ATP can work through phosphorylation, breaking a reaction down into two energetically favored steps connected by a phosphorylated …

NAD+/NADH is used as described in this video for transferring energy from the breakdown of food molecules to produce ATP through oxidative phosphorylation. The high energy electrons that …

In substrate-level phosphorylation, a phosphate group is transferred to ADP from another molecule.

When it's just an enzyme without any of this chemiosmosis that's driven by oxidation, like we learned in the electron transport chain, we call this substrate phosphorylation.

The reduced electron carriers— NADH and FADH 2 —generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will …
