Question

Draw a neat diagram and label the following diagram: Mitochondria which reaction is operated in mitochondria.

Answer 1

Hint: Mitochondria is a cell organelle that generates chemical energy. It is also called the powerhouse of the cell. The energy generated by the mitochondria is used by the cell for its biochemical reactions.

Complete answer:

The energy generated by mitochondria is stored in the form of ATP-Adenosine-triphosphate molecule. Mitochondria is membranes. Structure 8(i) Mitochondria have an inner and outer membrane space between the two membranes.
(ii) Porins are present in the outer membrane for movement of ions in and out of the mitochondria.
(iii) The folds increase the surface area of the membrane. This increased surface area is important because the inner membrane holds the proteins involved in the electron transport chain. These folds are known as cristae.

Reaction Operated in Mitochondria
Oxidative Phosphorylation: It is the process or reaction that is operated inside mitochondria. It is also called election transport linked phosphorylation.
It is a metabolic pathway where enzymes are used by the cells to oxidize nutrients and release the chemical energy of molecular oxygen which is used to produce ATP-adenosine triphosphate.
In this reaction, electrons are transferred (donor to acceptors)

Note: The process in which ATP is formed as a result of transfer of electrons from NADH to $[O_2]$ by series of electrons carriers.
Protein gradients are an inter-convertible currency of free energy in biological systems.
