Document Summary
Mitochondria: has inner and outer membrane with intermembrane space in between, main site of atp production, proteins of etc found in inner membrane, has its own genome and codes for some mitochondrial proteins, reproduce by fission. The inner membrane has folds that create the cristae seen in the matrix of the mitochondria. The cristae increase the surface area of the inner membrane where atp synthesis occurs. On the inner membrane is where atpase and the proteins of the etc convert nutrients into atp. The elaborate structure of the inner membrane increases the capacity to create atp. It changes shape, undergoes fission and fusion, and are always moving. A single mitochondria contains many mitochondrial genomes. During fission, the mitochondrion will split and create 2 new mitochondria with at least one mitochondrial genome in each. ***if a mitochondrion doesn"t receive a genome, it will degenerate and die*** Two mitochondria can also undergo fusion where two mitochondria will fuse.
