- Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
- Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
- Calcium Homeostasis. ...
- Regulation of Innate Immunity. ...
- Programmed Cell Death. ...
- Stem Cell Regulation.
_____________________________________
Mitochondria are mobile, plastic organelles that have a double-membrane structure. It ranges from 0.5 to 1.0 micrometer in diameter. It has four distinct domains: the outer membrane, the inner membrane, the intermembrane space, and the matrix.
The organelle is 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 intermembrane space is located between the inner and 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.
Both mitochondrial membranes are very rich in proteins.
