Respiration

To stay alive, cells need:

1. Food

2. Energy

3. To get rid of waste

4. To reproduce

• Respiration produces energy for cells.

• ALL organisms, including animals and plants, break down sugar into carbon dioxide and water.

• Chemical Equation for Respiration:

C6H12O6 + O2 H2O + CO2

• The cell uses the energy made by respiration to build, repair, and reproduce cells.

• Respiration occurs in the mitochondria.

Cellular Respiration

• When cells do not have enough oxygen to do respiration, they use fermentation to make energy.

• Fermentation breaks down sugar without oxygen and makes lactic acid as a waste product.

• Lactic acid is what makes your muscles burn when you work out really hard.
