Releasing the Stored Energy: Cellular Respiration

Cellular Respiration Breaking down nutrients in the prescence of oxygen to form usable energy (ATP). Used by unicellular and multicellular organisms. Used by plants and animals. Happens in the mitochondria

Cellular Respiration Glucose pyruvic acid water+ carbon dioxide+ 38ATP C6H12O6  P.A.  6H2O + 6 CO2 + 38ATP

Cellular Respiration has 3 stages Glycolysis The Citric Acid cycle The Electron Transport Chain

1. Glycolysis

Glycolysis Anaerobic (needs no oxygen) takes place in the cytoplasm uses up 2 ATP produces 4 ATP 2ATP + glucose  2 pyruvic acid + 4 ATP

2. The Citric Acid Cycle

The Citric Acid Cycle Aerobic (needs oxygen) takes place inside the mitochondria Produces 2 ATP

3. The Electron Transport Chain

The Electron Transport Chain Aerobic (needs oxygen) A series of complex reactions takes place in the membranes of the mitochondria produces 34 ATP
