Answer:
The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.[1] To date, only one eukaryote, Monocercomonoides, is known to have completely lost its mitochondria.
Explanation:
Structure of Mitochondria
Mitochondria are enclosed by two membranes—a smooth outer membrane and a markedly folded or tubular inner mitochondrial membrane, which has a large surface and encloses the matrix space.
The folds of the inner membrane are known as cristae, and tube-like protrusions are called tubules.
The intermembrane space is located between the inner and the outer membranes.
The number and shape of the mitochondria, as well as the numbers of cristae they have, can differ widely from cell type to cell type.
Tissues with intensive oxidative metabolism— e. g., heart muscle—have mitochondria with particularly large numbers of cristae.
Even within one type of tissue, the shape of the mitochondria can vary depending on their functional status.
Mitochondria are mobile, plastic organelles.
Functions of Mitochondria
The most important function of the mitochondria is to produce energy.
The simpler molecules of nutrition are sent to the mitochondria to be processed and to produce charged molecules.
These charged molecules combine with oxygen and produce ATP molecules. This process is known as oxidative phosphorylation.
Mitochondria help the cells to maintain proper concentration of calcium ions within the compartments of the cell.
