Document Summary
The mitochondria produces cellular energetics by accomplishing cellular respiration and oxidative phosphorylation. Mitochondria are crucial for many physiological, biochemical aspects of a cell s survival, growth and death. Mitochondria are essential for many physiological functions: metabolism. More than just production of atp and processing of nutrients o. Active process; there must be different things happening on the cell for it to die. There is a need for proper organized cell death. Important for tagged cells to die so you can reorganize and. Calcium is needed involved in a lot of these events. Has a lot of interfolds (cristae) to increase surface area. How do you study an organelle? o o. Subcellular fractionation: differential centrifugation, density gradient centrifugation o. Process of centrifugation: use different gradients, different buffers, different speeds so that you can isolate different components of the cell and break down the organelles into different areas o.
