In biology classes from high school through university, I learned that mitochondria are little objects that reside within ...

For example, biochemical reactions in a cell's mitochondria transfer energy from fatty acids and pyruvate molecules into an energy-rich molecule called adenosine triphosphate (ATP). Subsequently ...

The breakdown reactions that occur are catalysed by ... A pyruvate molecule enters the mitochondria and is broken down in the presence of oxygen to produce carbon dioxide and water.

Mitochondria arose through a fateful endosymbiosis more than 1.45 billion years ago. Many mitochondria make ATP without the help of oxygen. Aa Aa Aa What variety is there in mitochondria ...
