Unformatted text preview: 02.04.11 Lecture 8 - Mitochondria Mitochondria perform 2 functions within the cell 1. They are the primary sites for ATP synthesis in the cell 2. They have a key role in apoptosis- programmed cell death Mitochondria are actively transported along microtubules in some cells Mitochondria are anchored near sites of high ATP consumption in other cells QuickTime and a YUV420 codec decompressor are needed to see this picture. Mitochondria are dynamic organelles Relative contributions of nuclear and mitochondrial genes to protein composition Mitochondria are organized into 4 distinct compartments QuickTime and a MPEG-4 Video decompressor are needed to see this picture. Mitochondria are organized into 4 distinct compartments Compartments of a mitochondrion compared with a bacterium Mitochondria are organized into 4 distinct compartments Outer membrane: Perforated with large channels (porins) that allow entry of molecules < 5000 kD Enzymes involved in mitochondrial lipid synthesis...
