Mitochondria have an inner and outer membrane, with an intermembrane space between them. The outer membrane contains proteins known as porins, which allow movement of ions into and out of the mitochondrion. The inner membrane contains a variety of enzymes. …

Mitochondria’s primary function is to produce energy through the process of oxidative phosphorylation. Besides this, it is responsible for regulating the metabolic activity of the cell. It also promotes cell multiplication and cell growth. Mitochondria also detox ammonia in the liver cells.

The structure of the mitochondrion is adapted to the function it performs: Outer membrane – the outer membrane contains transport proteins that enable the shuttling of pyruvate from the cytosol. Cristae – the inner membrane is arranged into folds (cristae) that increase the SA:Vol ratio (more available surface)

They help turn the energy we take from food into energy that the cell can use. But, there is more to mitochondria than energy production. Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell.

Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.

Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Structure and Function of Mitochondria Cellular respiration. It is a well-known fact that mitochondria are responsible for cellular respiration. Cellular energy production. Mitochondria produce the energy as ATP (adenosine triphosphate) by oxidative phosphorylation. Calcium homeostasis. Promote cell cell growth and multiplication. Role in cell death. Oxidative radicals.

Mitochondria- Structure and Functions Mitochondria are oxygen-consuming ribbon-shaped cellular organelles of immense importance floating free throughout the cell. They are known as the “powerhouse of the cell” since these organelles supply all the necessary biological energy to the cell by oxidizing the substrates available.

The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle .

Functions of Mitochondria. The prime function of mitochondria is to produce energy . It is the power generation plant where the nutrients turn into ATP by a chemical process. The other major roles played by mitochondria are carrying out cellular metabolism. Through cellular metabolism, three major processes are carried. Conversion of food into energy
