Structure of Mitochondria . The cytoplasm of nearly all eukaryotic cells contain mitochondria, although there is at least one exception, the protist Chaos (Pelomyxa) carolinensis.They are especially abundant in cells and parts of cells that are associated with active processes.


The mitochondrial outer membrane can associate with the endoplasmic reticulum (ER) membrane, in a structure called MAM (mitochondria-associated ER-membrane). This is important in the ER-mitochondria calcium signaling and is involved in the transfer of lipids between the ER and mitochondria.


Mitochondria Structure Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix.


Mitochondria are called the 'powerhouse of the cell'. They contain a number of enzymes and proteins that help process carbohydrates and fats obtained from the food we eat to release energy. Read on to know about the structure and functions of the organelle.


Mitochondria are organelles that have a double membrane structure. The outer membrane defines the external shape of the mitochondrion. The inner membrane has many folds called cristae. (Cristae is the plural word for more than one crista.)The volume between the inner and outer membranes is called the intermembrane space, which is sometimes written "inter membrane space".


Structure of Mitochondria. Mitochondria have two membranes, an outer membrane and an inner membrane. These membranes are made of phospholipid layers, just like the cell’s outer membrane. The outer membrane covers the surface of the mitochondrion, while the inner membrane is located within and has many folds called cristae.


Mitochondria and chloroplasts are the powerhouses of the cell. Mitochondria appear in both plant and animal cells as elongated cylindrical bodies, roughly one micrometre in length and closely packed in regions actively using metabolic energy.


Structure of a mitochondrion. Mitochondria are bounded by a double-membrane system, consisting of inner and outer membranes. Folds of the inner membrane (cristae) extend into the matrix. (Micrograph by K. R. Porter/Photo Researchers, Inc.)


The structure of the mitochondria include the inner mitochondrial membrane, the outer mitochondrial membrane, the intermembrane space, the cristae, and then the mitochondrial matrix.


Structure and Function of Mitochondria. Mitochondria structure is quite compact, and all of its functions happen within this structure. Structure of mitochondria. They are sac-like double membranes structures present in the cytoplasm of the cell. They can be seen only under an electron microscope.
