Question

Oxysome of mitochondria are concerned with
A) Phosphorylation
B) Oxidative phosphorylation
C) Photorespiration
D) Digestion

Answer 1

Hint: Oxysomes were discovered by Fernandez Moran. These are the particles that are located on the surface of the folded inner membrane of the Mitochondria. Oxysomes are also known as F0-F1 particles. Oxysomes are made up of F1 head and F0 base and stalk. These are one of the small round bodies present in the folds of cristae. In each mitochondrion, the number of oxysomes varies from 104-105. These are chemically made up of the protein cortex and phospholipid core.

Complete answer:
The inner membrane of mitochondria has oxysomes.
Oxysomes take part in the synthesis of ATP through the process of oxidative phosphorylation.
The oxysomes are also known as ATP synthase.
The F0 part behaves as proton tunnels.
The stalk part of an elementary particle contains coupling factors.
Heads contain ATP as for the synthesis of ATP.
Phosphorylation is the process of addition of phosphate groups to an organic compound. Like the addition of phosphate to ADP to form ATP.
Photorespiration is a process where the RuBisCO enzyme oxygenates RuBP, wasting some energy produced by photosynthesis.
Digestion is the process of breakdown of large insoluble food particles into small water-soluble food particles for absorption into the watery blood plasma.

Hence, the correct answer is option B.

Additional Information: They play a significant role in the energy formation for the functioning of the cell.
F1 is called peripheral membrane protein and F0 is called an integral membrane protein.
Mitochondria organelles are the powerhouse of the cell because the energy required for the cell is produced and stored in the mitochondria in the form of ATP.
