Mitochondria

Mitochondria

Second largest organelle with unique genetic structure.- Double-layered outer membrane with inner folds called cristae.- Energy-producing chemical reactions take place on cristae- Controls level of water and other materials in cell.- Recycles and decomposes proteins, fats, and carbohydrates, and forms urea.

Structure:

Composed of modified double unit membrane (protein, lipid)- inner membrane infolded to form cristae Function - site of cellular respiration ie. the release of chemical energy from food Glucose + Oxygen -> Carbon Dioxide + Water + Energy (ATP)
