Mitochondria: Powerhouse of the Cell
Learning Objective
I can explain how mitochondria ended up in the cell, their function, their structure, and how their structure affects their function, as well as their origin, and how being from a bacterial cell influences it when given antibiotics
Key Concepts
Mitochondria have two membranes, an outer membrane that is permeable and an inner membrane where ATP is manufactured.
The widely accepted theory of how cells obtained mitochondria is called endosymbiosis, where one cell engulfed another, resulting in a mutually beneficial relationship.
Mitochondrial DNA is inherited from our mothers and does not recombine, so it can be used to study lineage.
