The structure and role of mitochondria (plural for mitochondrion). Discusses the outer membrane, inner membrane, cristae, porins, etc.
Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

@zangetsu6638 5 лет назад

there is often severe muscle wasting in people with cancer. one theory is called: Nuclear Meltdown, and it concerns mitochondria degradation. Michael Wiggs and his crew made a mouse model with implanted cancer cells and monitored the health of the mouse and many indications for four weeks, which is when the mice would be euthanized so they didn't die from the cancer. many of the indicators they monitored did NOT show a steady degradation, but instead would show minor degradation for the first three weeks, and then a LOT of degradation in the fourth week, and the mouse would be near death. But, when they monitored mitochondrial function, they noticed it degraded in a stepping stone fashion. this indicates that mitochondria show early changes we can investigate to see if we can intervene in the degradation process before severe muscle loss becomes deadly.

@jeff-onedayatatime.2870 3 года назад

I agree. My mind is boggled, I only recently found out mitochondria have different DNA than the cell nucleus. Somehow, this explains the origin of life. :)

@mechikaboombayah4960 5 лет назад

11:40 What he said about the spermatic mitochondria being dissolved by the egg... That's not what happens. Actually during fertilization only the nucleus of the sperm passes the layers of the egg and enter it. The tail and rest of the part of the sperm gets dissolved in the uterus (or more precisely the ampullary-isthmic junction of the fallopian tube cuz fertilization takes place over here)

I understand thriving mitochondria have not been found outside a cell. I suspect that they have not been removed from a cell and have survived.

@zeno7836 5 лет назад

Anthony Lusich the mitochondria is like a piece of history, they are ancestors of current day bacteria that descended from mitochondria that thrived. You cannot remove mitochondria from a cell and expect it to live, they are dependent on the cell for glycolysis in order to produce the energy we harvest.
