Answer to Question #88872 in Evolution for Phiroj Kumar bariha
Mitochondria are double membrane organelles that have the own genetic material and ribosomes, and it is mostly concerned with energy production..
The double membrane allows for creation of electrochemical gradient within the intermembrane space, which allows for further energy production.
The inner membrane has folds that increase the surface area for higher rate of processes associated with energy production.
The own genetic material and ribosomes allows for fast production of proteins needed by mitochondrion for its functioning.
