Extract

Peroxisome
* Eukaryotic organelle that degrades fatty acids and amino acids
* Also degrades the resulting hydrogen peroxide

Plant Central Vacuole - major storage space in center of plant cell with many functions
* Digestive - break down of macromolecules
* Storage - ions, sugars, amino acids, toxic waste
* Maintain cell rigidity - high ionic concentration generates high water potential

Mitochondria
* Found in ALL eukaryotic cells (yes, even in plant cells)
* Site of aerobic respiration
sugars + O2 - - > ATP + CO2 + H2O
* Contain DNA which codes for mitochondrial proteins, ribosomes, etc.
* Divide by a process similar to binary fission when cell divides
* Enclosed in a double membrane system
Inner Membrane forms the Cristae (invaginations into interior region)
*Site of energy generation
Matrix is the soluble portion of the mitochondira
* Site of carbon metabolism
* Location of mDNA
* Site of mitochondrial protein synthesis…
