Power house of cell

Cell organelles, like organs within the human body, each perform a specific function within the cell. Cells are the building blocks of all life on the planet and without cells humans along with millions of other species would not exist. There are many important organelles within a cell but one in particular is known as the “powerhouse” and for good reason. Mitochondria is an extremely important organelle found in most eukaryotic cells and is responsible for the production of Adenosine Triphosphate (ATP) which is a compound responsible for providing energy the fuels many of the processes of the cell. In this post we will take a closer look at the structure, function, and role in the innerworkings of a cell and its metabolism. Mitochondria Strcture Mitochondria shape and size is highly variable. Each mitochondrion has a limiting outer membrane that surrounds the organelle, an intermembrane space that separates the outer and inner membrane. It also has a matrix (similar to the cytoplasm but more viscous) that is enclosed by the inner membrane, and its own circular DNA and ribosomes in the matrix (figure 1). 1-F 0 ATP synthase protein produces the majority of the ATP used by the cells. The mitochondrial matrix is the site of mitochondrial DNA replication, transcription, protein biosynthesis and other enzymatic reactions (Munn 1974, Rogers 2010, Scheffler 2011, Kühlbrandt 2015, Know 2018).

Mitochondria are also heterogeneous, differing in structure and function. Dr Kasturi Mitra of the University of Alabama, Birmingham, Alabama, USA, leads a research team focused on understanding the relationship between structure and function of mitochondria, in both health and disease. Dr Mitra’s work has demonstrated that dynamic change in mitochondrial structure-f...
