Question

Which type of phosphorylation occurs in mitochondria?

Answer 1

Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a small molecule that stores mitochondrial chemical energy.

Complete answer:
During cellular respiration, mitochondria undergo oxidative phosphorylation. Because the energy of oxidation-reduction is used to create a proton gradient across the mitochondrial membrane, which is required for phosphorylation of ADP to form ATP, it is called oxidative phosphorylation.
The energy released by the oxidation of reducing powers NADH and FAD by transfer of their electrons through the electron transport chain to oxygen is used to drive the synthesis of ATP by ADP and Pi. The inner mitochondrial membrane contains an electron transport chain that transports electrons through a succession of carriers and pumps protons into the intermembrane gap. The final electron acceptor is oxygen, and the ensuing proton gradient provides energy for the ATP synthase enzyme to produce ATP.

Additional information:
Mitochondria functions:
Controls the cell's metabolic activities.
Encourages the formation of new cells and the multiplication of existing ones.
Aids in the detoxification of ammonia in liver cells.
Apoptosis (programmed cell death) is a process through which cells die.
It is responsible for the formation of some blood components as well as hormones such as testosterone and oestrogen.

Note:
The addition of a phosphate group to an organic substance is referred to as phosphorylation.
Proteins require phosphorylation to function properly. Because this causes a variety of modifications in different enzymes, which regulates their actions.
Depending on the type of organism, photophosphorylation, phosphorylation at the substratum level, and/or oxidative phosphorylation are used to convey energy and make ATP. Phosphorylation is the binding of a group of phosphates to a molecule.
The process of integrating a group of phosphates into an organic molecule is known as phosphorylation. It regulates pathways that control biological functions such cell death, cycle, development, and signal transduction.
