Question

Mitoplast is a preparation made from mitochondria. Justify the statement with reason.

Answer 1

Hint: A mitochondrion is a double membrane-bound oval-shaped organelle outer membrane and the inner membrane. But if the outer membrane is absent or less in mitochondria, then it is called mitoplast. It consists of the inner membrane and the matrix of a mitochondrion.

Complete Step by Step Answer:
Mitochondria is a double membrane-bound cell organelle found in most eukaryotic cells. They are known to be the powerhouse of the cell. Mitoplast is a preparation made from mitochondria in which the outer membrane is stripped away by the help of detergents and the inner membrane with the enclosed matrix is left intact. Mitoplasts have finger-like processes and can retain the capacity for oxidative phosphorylation.
Mitochondria are the filamentous, self-duplicating, double membranous cytoplasmic organelles of eukaryotic cells that deal with cellular respiration. They are the organelle which transmits energy found in all the aerobic eukaryotic cells. But secondarily they are lost in mature mammalian RBC mitochondria. They are also absent in prokaryotic cells where mesosomes serve as a mitochondrial replacement.
The matrix side of the inner membrane and cristae contains various tennis rackets such as the present particles called oxysomes. The mitochondria’s inner membrane contains oxysomes, electron transport chains, dehydrogenase succinate, and fatty acid biosynthesis enzymes. The oxysomes participate by oxidative phosphorylation in the synthesis of ATP. Therefore, they are the Mitochondria functional units.
Elementary particles, Parson's particle, Fernandez-Moran particle, F0 F1-particles, F0 F1-ATPase, H+ – ATPase, ATP synthetase, or ATP synthase are different names for oxysomes. A mitochondrion contains about 104-105 oxysomes, which are routinely positioned at 10 nm intervals. Oxysomes account for about 15 percent of the total protein in the inner membrane.

Note: Mitochondria are organelles that have important functions in oxidative phosphorylation, fatty acid oxidation, and apoptosis signaling. They have two distinct membranes mainly, outer membrane (OM) and inner membrane (IM). IM contains respiratory chain complexes that produce ATP.
