Mitochondria Aren't Just the Powerhouse of the Cell



Mitochondria are so much more than the powerhouse of the cell. In this episode, Patrick explores why this organelle is so unique and introduces new research that you probably didn’t hear about in school.

“The mitochondria is the powerhouse of the cell,” has got to be the most repeated line in biology. It has been firmly inserted into our middle school textbooks for years, and the powerhouse nickname stems from the mitochondria’s energy production capabilities, but the mitochondria offers so much more than that.

To start, when discussing all the mitochondria in our bodies, we use mitochondrion for singular, mitochondria for plural.

Each Mitochondrion looks different from cell to cell, and there are hundreds of thousands of mitochondria floating around in your cells—though that number also depends on what tissue we are referring to.

But, regardless of shape and number, all mitochondria do have some structural things in common: They each have two membranes—one outer layer, one inner layer, and some space in between them.

While the outer membrane works like a protective but permeable layer, letting different compounds in or out of the mitochondrion, the inner membrane is where some important biology happens to manufacture ATP (or Adenosine triphosphate, an organic compound that provides energy to drive processes in living cells).

So how did we develop mitochondria and what are all the things they do for our bodies?

“It’s one of the big mysteries of cell biology. Why do mitochondria—the oval-shaped structures that power our cells—have their own DNA, and why have they kept it when the cell itself has plenty of its own genetic material? A new study may have found an answer.”

  1. 6:22 "Sequencing that mitochondrial DNA and comparing genomes has allowed researchers to trace people back to a single female ancestor in Africa thousands of years ago"
    Wait what? Can someone give me a little clarification on it?

  2. i learned somewhere that the body is sort of a self tuning instrument. i think if the mitochondria(which for all intents and purposes is a separate entity within everyone) can be aware of cancer cells it reasons to think it may initiate a defense mechanic..the issue is it doesnt know and thinks the cure is the virus

  3. mitochondrial genom mean it is the birddings for inside the hole..bleesed for the dreanning is dryieng agean.,pasensya hindi ako marunong mag english never kase ako nag say sead of talking about english e..in hole of my life…dahil i hate english talking that it.,
