Mitochondria are often described as the powerhouses of cells, and this rather fascinating course offered at MIT looks into the role they play in human diseases. The materials here are from the Spring 2011 version of "Powerhouse Rules: The Role of Mitochondria in Human Diseases" taught by Professor Daniel Ferullo. The course is one of the advanced undergraduate seminars offered by MIT's Biology Department and MIT's OpenCourseWare, and visitors can look at the syllabus here, check out lecture summaries, and learn about some of the course assignments. This course also has a course study group feature where interested parties can submit questions or just look at the responses to previous questions. Additionally, visitors can download all of the course materials in one fell swoop, if they so desire.
