The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek μίτος, mitos, i.e. "thread", and χονδρίον—, chondrion, i.e. "granule" or "grain-like".
Mitochondria are commonly between 0.75 and 3μm in diameter but vary considerably in size and structure. Unless specifically stained, they are not visible. Mitochondria have been described as "the powerhouse of the cell" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth. Mitochondria have been implicated in several human diseases, including mitochondrial disorders,cardiac dysfunction, and heart failure. A recent University of California study including ten children diagnosed with severe autism suggests that autism may be correlated with mitochondrial defects.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

This video describes the structure and function of mitochondria.
Together Harvard University and XVIVO developed this 3D animation journey for Harvard's undergraduate Molecular and Cellular Biology students about the microscopic world of mitochondria. The animation highlights the creation of Adenosine Triphosphate (ATP) -- mobile molecules which store chemical energy derived from the breakdown of carbon-based food. ATP molecules act as a kind of currency, imparting chemical energy to power all the functional components of cellular activity. This piece is the second in a series of award winning animations XVIVO is creating for Harvard's educational website BioVisions at Harvard. The first program, Inner Life of the Cell, received international acclaim and can be seen both on our website and the BioVisions site. http://www.xvivo.net http://multimedia.mcb...
Mitochondria structure and function-This lecture explains about the structure and function of mitochondria. The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells.[1] The word mitochondrion comes from the Greek μίτος, mitos, i.e. "thread", and χονδρίον—, chondrion, i.e. "granule"[2] or "grain-like". Mitochondria are commonly between 0.75 and 3μm in diameter[3] but vary considerably in size and structure. Unless specifically stained, they are not visible. Mitochondria have been described as "the powerhouse of the cell" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.[4] In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signalin...
Mitochondria and the fatigue connection - How to boost your mitochondria and your energy! Schedule a FREE Consult: http://www.justinhealth.com/free-consultation Blog summary: Your mitochondria are the power houses of your cells that help generate energy. The energy your mitochondria produce is in the form of ATP which is important to feeling and performing great. There are 3 major causes of fatigue; adrenal imbalances, thyroid imbalances and mitochondrial insufficiency. Dr J will review the how you can test and assess your mitochondrial function as well as how to improve your mitochondrial performance. If you have chronic fatigue and aren’t sure the next steps to take, this video should help you connect the dots. ===================================== Gluten Video Series: http://www.ju...

A Google TechTalk, 12/09/16, presented by Matthew O'Connor ABSTRACT: "Engineering Approaches to Combating the Diseases and Disabilities of Aging: Rejuvenating the Mitochondria." This is a talk for a general audience on the work of the SENS Research Foundation to fight age related diseases with a focus on repairing the damage that accumulates as we age. The SENS Research Foundation recently published a paper on their research into repairing cells that lack two of the thirteen essential mitochondrial proteins. The SRF scientists were able to reengineer the two mitochondrial genes and move them to the nucleus of the cell, restoring the missing proteins. This work is significant for both its impact on treating age related diseases but also on childhood diseases resulting from a lack of certai...
