It is bounded by two sets of membranes, a smooth outer one and an inner one that is arranged in folds, or cristae, that extend into the interior of the mitochondrion, called the matrix. Mitochondria provide the principal source of cellular energy through oxidative phosphorylation and adenosine triphosphate synthesis. They also contain the enzymes involved with electron transport and the citric acid and fatty acid cycles.
Mitochondria Structure and Functions. 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.lthough mitochondria are present in every cell, they are found in high concentrations in the muscle cells that require more energy. Though the primary function of mitochondria is to produce energy, they also play an important role in the metabolism and synthesis of certain other substances in the body.
