Question

Oxysomes are located inside:

• A. Golgi body
• B. lysosomes
• C. plastids
• D. mitochondria

Hint:

The oxysome complex is composed of two main parts: the F0 unit, which spans the inner membrane, and the F1 unit, which protrudes into the matrix of the mitochondria. 

Answer 1

The Correct Option is D

Oxysomes or F₀-F₁ particles or elementary particles are located on the inner mitochondrial membrane.

They are responsible for ATP synthesis with the energy released during the electron transport system.

Hence, option D) mitochondria is the correct answer.

Answer 2

F₀-F₁ particles are also known as oxysomes or elementary particles. They are located in the inner mitochondrial membrane. They participate in oxidative phosphorylation and produce ATP.

Thus, the correct option is D.

Answer 3

Oxysomes or ATP synthase is an important enzyme found on the inner membrane of mitochondria. It is involved in the production of ATP (adenosine triphosphate), the main source of energy for cells. 

• Oxysomes act as molecular motors, using the energy from the movement of hydrogen ions across the inner membrane to produce ATP.
• The oxysome complex is composed of two main parts: the F0 unit, which spans the inner membrane, and the F1 unit, which protrudes into the matrix of the mitochondria. 
• The F0 unit is made up of a rotating cylinder of c subunits, which creates a flow of hydrogen ions from the intermembrane space to the matrix. 
• The flow of hydrogen ions through the F0 unit drives the rotation of the cylinder, which in turn drives the movement of the F1 unit.
• The F1 unit contains three catalytic sites, which are responsible for the synthesis of ATP. 
• When the F1 unit rotates, these catalytic sites interact with ADP (adenosine diphosphate) and inorganic phosphate, converting them into ATP. 
• This process is known as oxidative phosphorylation.

The ATP synthase complex is also involved in the maintenance of the electrochemical gradient across the inner membrane of the mitochondria. The gradient is maintained by the movement of hydrogen ions through the F0 unit and the pumping of protons by other transmembrane enzymes, such as the respiratory chain complexes.

Hence, oxysomes are located inside mitochondria.
